CHAPTER 14 SERIAL INTERFACE UART6
(10) Port mode register 11 (PM11)
This register sets port 11 input/output in 1-bit units.
When using the P112/SEG6/TXD6 pin for serial interface data output, clear PM112 to 0 and set the output latch of
P112 to 1.
When using the P113/SEG7/RXD6 pin for serial interface data input, set PM113 to 1. The output latch of P113 at
this time may be 0 or 1.
PM11 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
