DESCRIPTION
GPIO 6 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
6
PCIE_GPIO6_DATA
rw
This field is valid only if DN2_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 5 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
5
PCIE_GPIO5_DATA
rw
This field is valid only if DN2_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 4 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
4

PCIE_GPIO4_DATA
PCIE_GPIO3_DATA
PCIE_GPIO2_DATA
rw
rw
rw
This field is valid only if DN2_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 3 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 2 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
This field is valid only if DN1_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 1 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
1
PCIE_GPIO1_DATA
rw
This field is valid only if DN1_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 0 data.
GP Input mode: reads state of pin; writes have no effect
GP Output mode: reads and also controls state of pin
Program-selectable HP output pin
0
PCIE_GPIO0_DATA
rw
This field is valid only if DN1_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.
