19.3.2
The port B data register (PBDR) is an 8-bit readable/writable register that stores data for pins
PTB7 to PTB0. Bits PB7DT to PB0DT correspond to pins PTB7 to PTB0. When the pin function
is general output port, if the port is read the value of the corresponding PBDR bit is returned
directly. When the function is general input port, if the port is read the corresponding pin level is
read. Table 19.4 shows the function of PBDR.
PBDR is initialized to H'00 by a power-on reset. It retains its previous value in standby mode and
sleep mode, and in a manual reset.
