Section 35
35.5.2
PEDR is a register that stores data for pins PTE6 to PTE0. Bits PE6DT to PE0DT correspond to
pins PTE6 to PTE0. When the pin function is general output port, if the port is read, the value of
the corresponding PEDR bit is returned directly. When the function is general input port, if the
port is read the corresponding pin level is read.

Description
Reserved
This bit is always read as 0. The write value should always
be 0.
Table 35.5 shows the function of PEDR.
Write
Value is written to PEDR, but does not affect
pin state.
Write value is output from pin.
Value is written to PEDR, but does not affect
pin state.
Value is written to PEDR, but does not affect
