Bit0~Bit1: In crystal mode, these two bits are unused registers. In IRC or ERIC mode, PORT60 and PORT61 are
I/O direction control register.
Bit 2 ~ Bit 6 (IOC62 ~ IOC66) : PORT6(2~5) I/O direction control register
0
put the relative I/O pin as output
1
put the relative I/O pin into high impedance
Bit6~Bit7 (Unused): These2 bits must clear to 0 or MCU power consumption will increase.
The default value in these 2 bits are “1”. Please clear them to “0” when init MCU.
