8.11.2 Port B Output Data Register (PBODR)
PBODR stores output data for the port B pins.
Bit Bit Name Initial Value R/W Description
7 PB7DR 0 R/W
6 PB6DR 0 R/W
5 PB5DR 0 R/W
4 PB4DR 0 R/W
3 PB3DR 0 R/W
2 PB2DR 0 R/W
1 PB1DR 0 R/W
PBODR stores output data for the port B pins that are
used as the general output port.
0 PB0DR 0 R/W
8.11.3 Port B Input Data Register (PBPIN)
PBPIN indicates the states of the port B pins.
Bit Bit Name Initial Value R/W Description
7 PB7PIN Undefined* R
6 PB6PIN Undefined* R
5 PB5PIN Undefined* R
4 PB4PIN Undefined* R
3 PB3PIN Undefined* R
2 PB2PIN Undefined* R
1 PB1PIN Undefined* R
When this register is read, the pin states are read.
Since this register is allocated to the same address as
P8DDR, writing to this register writes data to P8DDR
and the port 8 setting is changed.
0 PB0PIN Undefined* R
Note: * The initial values are determined in accordance with the pin states of PB7 to PB0.
