Bit 0 (undefined): This bit is not used. However, it must be cleared to “0.” Otherwise,
the MCU power consumption will increase.
Bit 1 ~ Bit 2 (IOCC1 ~ IOCC2): PORTC (1~2) I/O direction control register
"0" : Set the corresponding I/O pin as output
"1" : Set the corresponding I/O pin to high impedance
Bit 3 ~ Bit 7 (undefined): This bit is not used. However, it must be cleared to “0.”
Otherwise, the MCU power consumption will increase.
NOTE
The default value of Bit 0 and Bits 3~7 is “1.” Clear to “0” when
initializing the MCU
