Table 4-39. Bit Descriptions – GPIO Data Register (continued)
BIT FIELD NAME ACCESS DESCRIPTION
GPIO 14 data.
GP Input mode: reads state of pin; writes have no affect
14 PCIE_GPIO14_DATA rw
GP Output mode: reads and also controls state of pin
This field is loaded from EEPROM (if present), and reset with FRST.
GPIO 13 data.
LED driver (see GPIO C Controls)
13 PCIE_GPIO13_DATA rw GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
This bit field is loaded from EEPROM (if present), and reset with FRST.
GPIO 12 data.
LED driver (see GPIO C Controls)
12 PCIE_GPIO12_DATA rw GP Input mode: reads state of pin; writes have no affect
GP Output mode: reads and also controls state of pin
This bit 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
11 PCIE_GPIO11_DATA rw 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
10 PCIE_GPIO10_DATA rw
Program-selectable HP input pin
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
9 PCIE_GPIO9_DATA rw
Program-selectable HP input pin
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
8 PCIE_GPIO8_DATA rw
Program-selectable HP output pin
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
7 PCIE_GPIO7_DATA rw 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.
