Section 35
35.13.2 Port P Data Register (PPDR)
PPDR is a register that stores data for pins PTP4 to PTP0. Bits PP4DT to PP0DT correspond to
pins PTP4 to PTP0. When the pin function is general output port, if the port is read, the value of
the corresponding PPDR bit is returned directly. When the function is general input port, if the
port is read, the corresponding pin level is read.

Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Table 35.13 shows the function of PPDR.
Write
Value is written to PPDR, but does not affect
pin state.
Write value is output from pin.
Value is written to PPDR, but does not affect
pin state.
