Another Chip Select Signal
Nov 27, 2007
I feel so lucky that we did not put all multi-purpose and unused pin definitions in standard AR1688 IP phone hardware reference design. Our customers can always think out of pin usage we never planned before.
We added UART support in software API because many customers found from schematics that UART pins is used as keypad, which means it can actually be used as UART.
And today we added CE3 support in software API because a customer found the chip select pin is not used, and this customer used it to drive more LEDs. I am expecting that more creative usage of CE3 pin will come out soon from different customers.
