CHAPTER 12: I/O Port
FM4 Peripheral Manual, Doc. No. 002-04856 Rev. *E 605
Notes:
− The "x" of PDORx is a wildcard. PDORx indicates PDOR0, PDOR1, PDOR2, etc.
− The "x" of Px0 and PxF is a wildcard. Px0 indicates P00, P10, P20, etc. PxF indicates P0F, P1F,
P2F, etc.
− One register allows setting output data of 16 ports from PxF to Px0.
− Each bit in the register sets each pin individually. There is a one-to-one correspondence between
bit assignment and the order of pins. For example, bit15 of PDOR0 sets P0F, bit14 of PDOR0
sets P0E, and bit0 of PDOR0 sets P00.
− For a pin which is not available in your product, must write initial value to the bit, and the read
value is undefined.
− The setting of P46 to P49 with this register is invalid. Use port output data register (VBDOR) of
VBAT RTC to set these pins. For details of VBAT, see VBAT Domain.
− PDORx register is not initialized by deep standby transition reset.
