Section 18 I/O Ports
18.2.2
Port B data register (PBDR) is an 8-bit read/write register that stores data for pins PTB7 to PTB0.
PB7DT to PB0DT bit corresponds to PTB7 to PTB0 pin. 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.
