8.12.2 Port B Output Data Register (PBODR)
PBODR stores output data for port B.
Bit Bit Name Initial Value R/W Description
7 PB7ODR 0 R/W
6 PB6ODR 0 R/W
5 PB5ODR 0 R/W
4 PB4ODR 0 R/W
3 PB3ODR 0 R/W
2 PB2ODR 0 R/W
1 PB1ODR 0 R/W
0 PB0ODR 0 R/W
PBODR can always be read or written to,
regardless of the contents of PBDDR.

Reading PBPIN always returns the pin states.
PBPIN has the same address as P8DDR. If a
write is performed, data will be written to P8DDR
and the port 8 settings will change.
Note: * The initial value is determined according to the PB7 to PB0 pin states.
