Section 35
35.16.2 Port T Data Register (PTDR)
PTDR is a register that stores data for pins PTT4 to PTT0. Bits PT4DT to PT0DT correspond to
pins PTT4 to PTT0. When the pin function is general output port, if the port is read, the value of
the corresponding PTDR 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 35.16 shows the function of PTDR.
Write
Value is written to PTDR, but does not affect
pin state.
Write value is output from pin.
Value is written to PTDR, but does not affect
pin state.
