Port N
Port N is an 8-bit input/output port with the pin configuration shown in figure 20.13. Each pin has
an input pull-up MOS, which is controlled by the port N control register (PNCR) in the PFC.

Register Description
Port N has the following register. For details on the register address and access size, see section
24, List of Registers.

Port N data register (PNDR)
20.13.2
Port N Data Register (PNDR)
PNDR is an 8-bit readable/writable register that stores data for pins PTN7 to PTN0. Bits PN7DT
to PN0DT correspond to pins PTN7 to PTN0. When the pin function is general output port, if the
port is read, the value of the corresponding PNDR bit is returned directly. When the function is
general input port, if the port is read, the corresponding pin level is read.
