40.2.36 Port N Pull-Up Control Register (PNPUPR)
PNPUPR is an 8-bit readable/writable register. Each bit of this register corresponds to PTN7 to
PTN0, and when the pins of Port N are used by “other function”, pull-up control is performed for
the individual pins. The settings in this register are invalid for the pins specified to function as port
pins by PNCR.
