10.11.4 Port C Pull-Up MOS Control Register (PCPCR)
PCPCR controls on/off of the input pull-up MOS for port C. PCPCR is valid in modes 4 and 7.
Bit Bit Name Initial Value R/W Description
7 PC7PCR 0 R/W
6 PC6PCR 0 R/W
5 PC5PCR 0 R/W
4 PC4PCR 0 R/W
3 PC3PCR 0 R/W
2 PC2PCR 0 R/W
1 PC1PCR 0 R/W
0 PC0PCR 0 R/W
When in a input port state, setting the
corresponding bit to 1 turns on the input pull-up
MOS for that pin.
10.11.5 Port C Open Drain Control Register (PCODR)
PCODR specifies the output type of each port C pin.
Bit Bit Name Initial Value R/W Description
7 PC7ODR 0 R/W
6 PC6ODR 0 R/W
5 PC5ODR 0 R/W
4 PC4ODR 0 R/W
3 PC3ODR 0 R/W
2 PC2ODR 0 R/W
1 PC1ODR 0 R/W
0 PC0ODR 0 R/W
When not specified for address output, setting a
PCODR bit to 1 makes the corresponding pin an
NMOS open-drain output pin, while clearing a
PCODR bit to 0 makes the corresponding pin a
CMOS output pin.
