(a) power on the board then load the code, led3 should toggle fast if not
press reset button.
(b) press the user button key to execute the ip-code called in main.c file.
(c) if macro "use_slib_function" is defined and slib is never enabled, go
to step(e).
(d) if the ip-code is successfully executed, the green led4 should toggle
continuously. else the red led2 toggles continuously.
(e) the slib_enable() function will set slib configuration once the ip-code
is correctly executed. the green led4 will turn on some time and then
a system rest is executed to activate slib. the code will run to step(b).
(c) if the ip-code is successfully executed, the green led4 should toggle
continuously. else the red led2 toggles continuously.
for details, please refer to the application note document AN0065.
