I use LPC51U68 with OM40005 board, is there examples that I can follow?
LPC51U68 is used as Master and another device as slave communicate via SPI.
After some initiation steps, I want to let LPC51U68 enter sleep mode or deep-sleep mode then stand by a interrupt from external GPIO pin. (Is a specific GPIO pin need to be selected?)
When receive a interrupt, LPC51U68 needs to configure the status of other GPIO pin.
