b7 b6 b5 b4 b3 b2
NOTES:
1. Set the corresponding port direction bit for each CLKi pin to "0" (input mode).
2. To receive data, set the corresponding port direction bit for each RxDi pin to "0" (input mode).
UART2 Transmit/receive Mode Register
b7 b6 b5 b4 b3 b2
NOTES:
1. Set the corresponding port direction bit for each CLK2 pin to "0" (input mode).
2. To receive data, set the corresponding port direction bit for each RxD2 pin to "0" (input mode).
3. Set the corresponding port direction bit for SCL
