28.2.35 Port J Pull-Up Control Register (PJPUPR) PJPUPR is an 8-bit readable/writable register that performs the pull-up control for each of the port J7 to J0 (PJ7 to PJ0) pins when the port J pins are used by peripheral modules. When the port J pins are used by the GPIO, the setting for this register is ignored.
