10.13.2 Port E Data Register (PEDR)
PEDR stores output data for the port E pins.
Bit Bit Name Initial Value R/W Description
7 PE7DR 0 R/W
6 PE6DR 0 R/W
5 PE5DR 0 R/W
4 PE4DR 0 R/W
3 PE3DR 0 R/W
2 PE2DR 0 R/W
1 PE1DR 0 R/W
Output data for a pin is stored when the pin function
is specified to a general purpose I/O.

10.13.3 Port E Register (PORTE)
PORTE shows port E pin states.
PORTE cannot be modified.
Bit Bit Name Initial Value R/W Description

If a port E read is performed while PEDDR bits are
set to 1, the PEDR values are read. If a port E read
is performed while PEDDR bits are cleared to 0, the
pin states are read.
0 PE0 ⎯* R
Note: * Determined by the states of pins PE7 to PE0.
