Section 9 I/O Ports
Port B Data Register (PBDR)
PBDR is an 8-bit readable/writable register that stores output data for pins PB7 to PB0. When a bit
in PBDDR is set to 1, if port B is read the value of the corresponding PBDR bit is returned. When
a bit in PBDDR is cleared to 0, if port B is read the corresponding pin level is read.
Bit
Initial value
Read/Write
PBDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
