Section 35
35.10.2 Port K Data Register (PKDR)
PKDR is a register that stores data for pins PTK3 to PTK0. Bits PK3DT to PK0DT correspond to
pins PTK3 to PTK0. When the pin function is general output port, if the port is read, the value of
the corresponding PKDR 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 35.10 shows the function of PKDR.
Write
Value is written to PKDR, but does not affect
pin state.
Write value is output from pin.
Value is written to PKDR, but does not affect
pin state.
