Note:
output mode (selected in port3 control register), status of corresponding pin is fixed, regardless the contents of Port3
register (P3D)
High-impedance output mode: High-impedance
P-channel open drain output mode: High-impedance
N-channel open drain output mode: Fixed to “L”
CMOS output mode: High-impedance: Fixed to “L”
When using RC-ADC as the secondary function, specify each pin be “High-impedance input” even the RC oscillation
monitor pin. Pull-up or Pull-down input makes drawing the current.
If any bit combination out of the above is set to “Prohibited” and the corresponding bit of the port 3 is sepecified to
The P32MD1 and P32MD0 bits are used to select the primary or secondary function of the P32 pin.
The P31MD1 and P31MD0 bits are used to select the primary or secondary function of the P31 pin.
The P30MD1 and P30MD0 bits are used to select the primary or secondary function of the P30 pin.
