28. General Purpose I/O Ports (GPIO)
28.2.33 Port E Pull-Up Control Register (PEPUPR)
PEPUPR is an 8-bit readable/writable register that performs the pull-up control for each of the port
E3 and E0 (PE3 and PE0) pins when the pins are used by peripheral modules. When the port E
pins are used by the GPIO, the setting for this register is ignored.
