Port P82 data bit Depends on how the Port Direction Register is set
3 P83DT • If direction bit = "0" (input mode)
Port P83 data bit 0: Port input pin = "low"
4 P84DT 1: Port input pin = "high"
Port P84 data bit • If direction bit = "1" (output mode) (Note 1)
5 P85DT 0: Port output latch = "0" / Port pin level = "low"
Port P85 data bit 1: Port output latch = "1" / Port pin level = "high"
6 P86DT At write
Port P86 data bit Write to the port output latch
7 P87DT
Port P87 data bit
