Section 35
35.18.2 Port V Data Register (PVDR)
PVDR is a register that stores data for pins PTV4 to PTV0. Bits PV4DT to PV0DT correspond to
pins PTV4 to PTV0. When the pin function is general output port, if the port is read, the value of
the corresponding PVDR 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 35.18 shows the function of PVDR.
Write
Value is written to PVDR, but does not affect
pin state.
Write value is output from pin.
Value is written to PVDR, but does not affect
pin state.
