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”.
Bits P3_0 to P3_2 and P3_6 in the P3 register are unavailable on this MCU. 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”.
Bits P4_0 to P4_4 in the P4 register are unavailable on this MCU. If it is necessary to set bits P4_0 to P4_4, set to
“0” (“L” level). When read, the content is “0”.

0 : Input mode
1 : Output mode
The pin level on any I/O port w hich is set
for input mode can be read by reading the
corresponding bit in this register. The pin
level on any I/O port w hich is set for
output mode can be controlled by w riting
to the corresponding bit in this register.
