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. While port
B acts as an output port, the value of this register is output. 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.
PBDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
