Port E

Port E is a 5-bit input port. Port E pins also function as the LPC input pins and emulator
input/output pins. Port E has the following registers.

• Port E input pull-up MOS control register (PEPCR)

• Port E input data register (PEPIN)

8.14.1 Port E Input Pull-Up MOS Control Register (PEPCR)
PEPCR specifies each bit in input pull-up MOS on/off.
Bit Bit Name
7 to 5 
4 PE4PCR
3 PE3PCR
2 PE2PCR
1 PE1PCR
0 PE0PCR
8.14.2 Port E Input Data Register (PEPIN)
PEPIN indicates the pin states of port E.
Bit Bit Name
7 to 5 
4 PE4PIN
