Port B Data Register (PBDR)
PBDR is an 8-bit readable/writable register that stores output data for the port B pins (PB
PBDR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its prior
state after a manual reset, and in software standby mode.
Port B Register (PORTB)
PORTB is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port B pins (PB
If a port B read is performed while PBDDR bits are set to 1, the PBDR values are read. If a port B
read is performed while PBDDR bits are cleared to 0, the pin states are read.
After a power-on reset and in hardware standby mode, PORTB contents are determined by the pin
states, as PBDDR and PBDR are initialized. PORTB retains its prior state after a manual reset, and
in software standby mode.
