10.13.4 Port E Pull-Up MOS Control Register (PEPCR)
PEPCR controls on/off of the input pull-up MOS for port E. PEPCR is valid in 8-bit bus mode.
Bit Bit Name Initial Value R/W Description
7 PE7PCR 0 R/W
6 PE6PCR 0 R/W
5 PE5PCR 0 R/W
4 PE4PCR 0 R/W
3 PE3PCR 0 R/W
2 PE2PCR 0 R/W
1 PE1PCR 0 R/W
0 PE0PCR 0 R/W
When PEDDR = 0 (input port), setting the
corresponding bit to 1 turns on the input pull-up
MOS for that pin.
10.13.5 Port E Open Drain Control Register (PEODR)
PEODR specifies the output type of each port E pin.
Bit Bit Name Initial Value R/W Description
7 PE7ODR 0 R/W
6 PE6ODR 0 R/W
5 PE5ODR 0 R/W
4 PE4ODR 0 R/W
3 PE3ODR 0 R/W
2 PE2ODR 0 R/W
1 PE1ODR 0 R/W
0 PE0ODR 0 R/W
When not specified for data or address output,
setting a PEODR bit to 1 makes the corresponding
pin an NMOS open-drain output pin, while clearing
a PEODR bit to 0 makes the corresponding pin a
CMOS output pin.
