P7.[7:0]: Port7 Output Latch Bits.
Write - Output appears on I/O pins.
0: Logic Low Output.
1: Logic High Output (Open-Drain if corresponding P7MDOUT bit = 0). See SFR Definition
17.23.
Read - Returns states of I/O pins.
0: P7.n pin is logic low.
1: P7.n pin is logic high.
P7.[7:0] can be driven by the External Data Memory Interface (as AD[7:0] in Multiplexed
mode, or as D[7:0] in Non-multiplexed mode). See
Interface and On-Chip XRAM” on page 187
ory Interface.
P7MDOUT.[7:0]: Port7 Output Mode Bits.
0: Port Pin output mode is configured as Open-Drain.
1: Port Pin output mode is configured as Push-Pull.
SDA, SCL, and RX0 (when UART0 is in Mode 0) and RX1 (when UART1 is in Mode 0) are
always configured as Open-Drain when they appear on Port pins.
