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.
