Bit Name

Function

0(8)

Pn0DT

Port Pn0 data bit

Depends on how the Port Direction Register is set

1(9)

Pn1DT

If direction bit = "0" (input mode)

Port Pn1 data bit

0: Port input pin = "L"

2(10)

Pn2DT

1: Port input pin = "H"

Port Pn2 data bit

If direction bit = "1" (output mode) (Note 1)

3(11)

Pn3DT

0: Port output latch = "0" / Port pin level = "L"

Port Pn3 data bit

1: Port output latch = "1" / Port pin level = "H"

4(12)

Pn4DT

Port Pn4 data bit

Write to the port output latch

5(13)

Pn5DT

Port Pn5 data bit

6(14)

Pn6DT

Port Pn6 data bit

7(15)

Pn7DT

Port Pn7 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).

Notes: • Following bits are not provided (read as "0," writing has no effect):

P40, P60, P65–P67, P90–P92, P120–P123, P151, P152, P154–P157, P170–P173, P176, P177, P222, P223, P226, P227

• The SBI# pin input level can be read out by reading the P64DT bit. Writing to the P64DT bit has no effect.

• The MOD0 and MOD1 pin input levels can be read out by reading the P80DT and P81DT bits, respectively. Writing to the

P80DT and P81DT bits has no effect.

• P221 is an input-only port. Writing to the P221DT bit has no effect.
