 ## Why choose CherryUSB
 
-### Easy to study USB
+### Easy to Learn USB
 
-In order to make it easier for users to learn USB basics, enumeration, driver loading and IP drivers, the code has been written with the following advantages:
+To facilitate user learning of USB fundamentals, enumeration, driver loading, and IP drivers, the written code has the following advantages:
 
-- Lean code, simple logic, no complex C syntax
-- Tree-based programming with cascading code
-- Class-drivers and porting-drivers are templating and simplification
-- Clear API classification (slave: initialisation, registration api, command callback api, data sending and receiving api; host: initialisation, lookup api, data sending and receiving api)
+- Streamlined code with simple logic and no complex C language syntax
+- Tree-structured programming with progressive code layers
+- Templated and simplified Class drivers and porting drivers
+- Clear API categorization (Device: initialization, class registration, command callbacks, data transmission; Host: initialization, class discovery, data transmission)

-In order to facilitate the use of the USB interface and to take into account the fact that users have learned about uart and dma, the following advantages have been designed for the data sending and receiving class of interface:
+To facilitate user interaction with USB interfaces, considering users’ familiarity with UART and DMA, the designed data transmission interface has the following advantages:
 
-- Equivalent to using uart tx dma/uart rx dma
-- There is no limit to the length of send and receive, the user does not need to care about the USB packetization process (the porting driver does it)
+- Equivalent to using UART TX DMA/UART RX DMA
+- No length restrictions on transmission/reception; users don’t need to worry about USB packetization (porting drivers handle packetization)
 
-### Easy to bring out USB performance
+### Easy to Achieve USB Performance
 
-Taking into account USB performance issues and trying to achieve the theoretical bandwidth of the USB hardware, the design of the data transceiver class interface has the following advantages:
+Considering USB performance requirements to reach theoretical USB hardware bandwidth, the designed data transmission interface has the following advantages:
 
-- Porting drivers directly to registers, no abstraction layer encapsulation
+- Porting drivers directly interface with registers without abstraction layer encapsulation
 - Memory zero copy
-- If IP has DMA then uses DMA mode (DMA with hardware packetization)
-- Unlimited length make it easier to interface with hardware DMA and take advantage of DMA
-- Packetization is handled in interrupt
+- DMA mode used when IP supports DMA (DMA provides hardware packetization functionality)
+- No length restrictions, facilitating hardware DMA interfacing and maximizing DMA advantages
+- Packetization handled in interrupt context

+ * wIndex:         Port
+ * wLength:        0
+ * Data:           None
+ * The BaudDivisor values are calculated as follows:
+ * - BaseClock is either 12000000 or 48000000 depending on the device.
+ *   FIXME: I wish I knew how to detect old chips to select proper base clock!
+ * - BaudDivisor is a fixed point number encoded in a funny way.
+ *   (--WRONG WAY OF THINKING--)
+ *   BaudDivisor is a fixed point number encoded with following bit weighs:
+ *   (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
+ *   end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
+ *   (--THE REALITY--)
+ *   The both-bits-set has quite different meaning from 0.75 - the chip
+ *   designers have decided it to mean 0.125 instead of 0.75.
+ *   This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
+ *   and Flow Control Consideration for USB to RS232".
+ * - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
+ *   automagically re-encode the resulting value to take fractions into
+ *   consideration.
+ * As all values are integers, some bit twiddling is in order:
+ *   BaudDivisor = (BaseClock / 16 / BaudRate) |
+ *   (((BaseClock / 2 / BaudRate) & 4) ? 0x4000    // 0.5
+ *    : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000  // 0.25
+ *    : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000  // 0.125
+ *    : 0)
+ *
+ * For the FT232BM, a 17th divisor bit was introduced to encode the multiples
+ * of 0.125 missing from the FT8U232AM.  Bits 16 to 14 are coded as follows
+ * (the first four codes are the same as for the FT8U232AM, where bit 16 is
+ * always 0):
+ *   000 - add .000 to divisor
+ *   001 - add .500 to divisor
+ *   010 - add .250 to divisor
+ *   011 - add .125 to divisor
+ *   100 - add .375 to divisor
+ *   101 - add .625 to divisor
+ *   110 - add .750 to divisor
+ *   111 - add .875 to divisor
+ * Bits 15 to 0 of the 17-bit divisor are placed in the urb value.  Bit 16 is
+ * placed in bit 0 of the urb index.
+ *
+ * Note that there are a couple of special cases to support the highest baud
+ * rates.  If the calculated divisor value is 1, this needs to be replaced with
+ * 0.  Additionally for the FT232BM, if the calculated divisor value is 0x4001
+ * (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
+ * not supported by the FT8U232AM).
