DESCRIPTION
GPIO 14 data.
GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
This field is loaded from EEPROM (if present), and reset with FRST.

GPIO 11 data.
GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
Program-selectable HP input or output pin
This bit field is loaded from EEPROM (if present), and reset with FRST.
GPIO 10 data.
GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
Program-selectable HP input pin
10
PCIE_GPIO10_DATA
rw
This field is valid only if DN3_DPSTRP == 0. If this bit field is valid then it is loaded from
EEPROM (if present), and reset with FRST. If this field is invalid, it is a read-only bit
field.
GPIO 9 data.
GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
Program-selectable HP input pin
9
PCIE_GPIO9_DATA
rw
This field is valid only if DN3_DPSTRP == 0. If this bit field is valid then it is loaded from
EEPROM (if present), and reset with FRST. If this field is invalid, it is a read-only bit
field.
GPIO 8 data.
GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
Program-selectable HP output pin

rw
This field is valid only if DN3_DPSTRP == 0. If this bit field is valid then it is loaded from
EEPROM (if present), and reset with FRST. If this field is invalid, it is a read-only bit
field.
GPIO 7 data.
GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
GP Output mode: reads and also controls state of pin
This bit field is loaded from EEPROM (if present), and reset with FRST.
