9.10.4 Port E Pull-Up MOS Control Register (PEPCR)
PEPCR controls on/off states of the input pull-up MOS of port E.
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
When the pin is in the input state, the input pull-up MOS
of the input pin is on when the corresponding bit is set to
1.
0 PE1PCR 0 R/W
