The port B data register (PBDR) is a 16-bit readable/writable register that stores port B data. Bits
PB15DR to PB0DR correspond to pins PB15/PULS5/SCK2 to PB0/TO6A.
When a pin functions as a general output, if a value is written to PBDR, that value is output
directly from the pin, and if PBDR is read, the register value is returned directly regardless of the
pin state.
When a pin functions as a general input, if PBDR is read the pin state, not the register value, is
returned directly. If a value is written to PBDR, although that value is written into PBDR it does
not affect the pin state. Table 19.4 summarizes port B data register read/write operations.
PBDR is initialized to H'0000 by a power-on reset (excluding a WDT power-on reset), and in
hardware standby mode. It is not initialized in software standby mode or sleep mode.
