Port P82 data bit
Depends on how the Port Direction Register is set
P83DT
• If direction bit = "0" (input mode)
0: Port input pin = "low"
Port P83 data bit
P84DT
1: Port input pin = "high"
Port P84 data bit
• If direction bit = "1" (output mode) (Note 1)
P85DT
0: Port output latch = "0" / Port pin level = "low"
1: Port output latch = "1" / Port pin level = "high"
Port P85 data bit
P86DT
At write
Port P86 data bit
Write to the port output latch
P87DT
Port P87 data bit
Note 1: To select the port data to read, use the Port Input Special Function Control Register’s port input data select bit (PISEL).
