1. Bits P3_0 to P3_2, and P3_6 in the P3 register are unavailable on this MCU.
Bits PD3_0 to PD3_2, and PD3_6 in the PD3 register are unavailable on this MCU.
If it is necessary to set bits PD3_0 to PD3_2, and PD3_6, set to 0 (input mode). When read, the content is 0.
Bits PD4_0 to PD4_4, PD4_6, and PD4_7 in the PD4 register are unavailable on this MCU. If it is necessary to set bits
PD4_0 to PD4_4, PD4_6, and PD4_7, set to 0 (input mode). When read, the content is 0.
If it is necessary to set bits P3_0 to P3_2, and P3_6, set to 0 (“L” level). When read, the content is 0.

The pin level of any I/O port w hich is set
to input mode can be read by reading the
corresponding bit in this register. The pin
level of any I/O port w hich is set to output
mode can be controlled by w riting to the
corresponding bit in this register.
