10.12.4 Port D Pull-Up MOS Control Register (PDPCR)
PDPCR controls on/off of the input pull-up MOS for port D. PDPCR is valid in mode 7.
Bit Bit Name Initial Value R/W Description
7 PD7PCR 0 R/W
6 PD6PCR 0 R/W
5 PD5PCR 0 R/W
4 PD4PCR 0 R/W
3 PD3PCR 0 R/W
2 PD2PCR 0 R/W
1 PD1PCR 0 R/W
0 PD0PCR 0 R/W
When PDDDR = 0 (input port), setting the
corresponding bit to 1 turns on the input pull-up
MOS for that pin.
10.12.5 Port D Open Drain Control Register (PDODR)
PDODR specifies the output type of each port D pin.
Bit Bit Name Initial Value R/W Description
7 PD7ODR 0 R/W
6 PD6ODR 0 R/W
5 PD5ODR 0 R/W
4 PD4ODR 0 R/W
3 PD3ODR 0 R/W
2 PD2ODR 0 R/W
1 PD1ODR 0 R/W
0 PD0ODR 0 R/W
When not specified for data or address output,
setting a PDODR bit to 1 makes the corresponding
pin an NMOS open-drain output pin, while clearing
a PDODR bit to 0 makes the corresponding pin a
CMOS output pin.
