When port B functions 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 logic level is read. Bit Initial value Read/Write 0 PB 0 R/W 0 1 PB 0 R/W 1 2 PB 0 R/W 2 3 PB 0 R/W 3 4 PB 0 R/W 4 5 PB 0 R/W 5 6 PB 0 R/W 6 7 PB 0 R/W 7 Port B data 7 to 0 These bits store data for port B pins PBDR is initialized to H'00 by a reset and in hardware standby mode.
