Section 20 I/O Ports
20.2.3 Port A Port Registers H, L (PAPRH, PAPRL)
PAPRH and PAPRL are 16-bit read-only registers, in which bits PA25PR to PA16PR, PA13PR to
PA11PR, and PA9PR to PA0PR correspond to pins PA25/CE2B/DACK3/POE8/PINT7 to
PA16/WE3/DQMUU/ICIOWR/AH/DREQ2/CKE, PA13/WE1/DQMLU/WE/POE7 to
PA11/CS1/POE5, and PA9/TCLKD/IRQ3/FRAME/CKE to PA0/RxD0/PINT0/CS4, respectively.
PAPRH and PAPRL always return the states of the pins regardless of the PFC setting.
