Port B Data Register (PBDR)
PBDR is an 8-bit readable/writable register that stores output data for the port B pins (PB7 to
PB0). PBDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior
state in software standby mode.
Port B Register (PORTB)
Note: * Determined by state of pins PB7 to PB0.
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 (PB7 to PB0) must always be performed on PBDR.
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 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 in software standby mode.
