28. General Purpose I/O Ports (GPIO)
28.2.39 Port N Pull-Up Control Register (PNPUPR)
PNPUPR is an 8-bit readable/writable register that performs the pull-up control for each of the
port N7 to N0 (PN7 to PN0) pins when the port N pins are used by peripheral modules. When the
port N pins are used by the GPIO, the setting for this register is ignored.
Note: n = 7 to 0
