Section 35
35.2.2
PBDR is a 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.
