10.10.4 Port B Pull-Up MOS Control Register (PBPCR)
PBPCR controls on/off of the input pull-up MOS for port B. PBPCR is valid in modes 4 and 7.
Bit Bit Name Initial Value R/W Description
7 PB7PCR 0 R/W
6 PB6PCR 0 R/W
5 PB5PCR 0 R/W
4 PB4PCR 0 R/W
3 PB3PCR 0 R/W
2 PB2PCR 0 R/W
1 PB1PCR 0 R/W
0 PB0PCR 0 R/W
When in a input port register state, setting the
corresponding bit to 1 turns on the input pull-up
MOS for that pin.
10.10.5 Port B Open Drain Control Register (PBODR)
PBODR specifies the output type of each port B pin.
Bit Bit Name Initial Value R/W Description
7 PB7ODR 0 R/W
6 PB6ODR 0 R/W
5 PB5ODR 0 R/W
4 PB4ODR 0 R/W
3 PB3ODR 0 R/W
2 PB2ODR 0 R/W
1 PB1ODR 0 R/W
0 PB0ODR 0 R/W
When not specified for address output, setting a
PBODR bit to 1 makes the corresponding pin an
NMOS open-drain output pin, while clearing a
PBODR bit to 0 makes the corresponding pin a
CMOS output pin.
