Section 35
35.15.2 Port S Data Register (PSDR)
PSDR is a register that stores data for pins PTS4 to PTS0. Bits PS4DT to PS0DT correspond to
pins PTS4 to PTS0. When the pin function is general output port, if the port is read, the value of
the corresponding PSDR 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 35.15 shows the function of PSDR.
Write
Value is written to PSDR, but does not affect
pin state.
Write value is output from pin.
Value is written to PSDR, but does not affect
pin state.
