D Bit Name
0 Pn0DT (Port Pn0 data)
1 Pn1DT (Port Pn1 data)
2 Pn2DT (Port Pn2 data)
3 Pn3DT (Port Pn3 data)
4 Pn4DT (Port Pn4 data)
5 Pn5DT (Port Pn5 data)
6 Pn6DT (Port Pn6 data)
7 Pn7DT (Port Pn7 data)
Note 1: The following bits have no functions assigned (when read, the bit = 0; writing to the bit has no effect).
Note 2: Port P64 is input mode-only. Writing to the P64DT bit has no effect.
Note 3: Port P221 is input mode-only. Writing to the P221DT bit has no effect.
Note 4: Ports P80 and P81 are input mode-only. Writing to the P80DT and P81DT bits has no effect. When
read out, P80 shows the MOD0 pin level and P81 shows the MOD1 pin level. The P80DT and P81DT
bits are write-protected.

Function
Depending on how the Port Direction Register is set
• When direction bit = 0 (input mode)
0: Port input pin = low
1: Port input pin = high
• When direction bit = 1 (output mode)
0: Port output latch = low
1: Port output latch = high
