40.2.33 Port K Pull-Up Control Register (PKPUPR)
PKPUPR is an 8-bit readable/writable register. Each bit of this register corresponds to PTK7 to
PTK0, and when the pins of Port K 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 PKCR.
