Port H Pull-Up Control Register (PHPUPR)
PHPUPR is an 8-bit readable/writable register that performs the pull-up control for each of the
port H7 to H0 (PH7 to PH0) pins when the port H pins are used by peripheral modules. When the
port H pins are used by the GPIO, the setting for this register is ignored.
