(2) Port E Output Data Register (PEODR)
PEODR stores output data for the port E pins.
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
The PEODR register stores the output data for the
pins that are used as the general output port.
(3) Port E Input Data Register (PEPIN)
PEPIN indicates the pin states of port E.
Bit Bit Name Initial Value R/W Description
7 PE7PIN Undefined* R
6 PE6PIN Undefined* R
5 PE5PIN Undefined* R
4 PE4PIN Undefined* R
3 PE3PIN Undefined* R
2 PE2PIN Undefined* R
1 PE1PIN Undefined* R
0 PE0PIN Undefined* R
When this register is read, the pin states are read.
Since this register is allocated to the same address as
PEDDR, writing to this register writes data to PEDDR
and the port E setting is changed.
Note: The initial value of these pins is determined in accordance with the state of pins PE7 to
PE0.
