Reserved
LED[3:1] enable (LEDx_EN). A ‘1’ sets the associated pin as an LED
output. When cleared low, the pin functions as a GPIO signal.
Reserved
GPIO Interrupt Polarity 0-2 (GPIO_INT_POL). When set high, a high logic
level on the corresponding GPIO pin will set the corresponding INT_STS
register bit. When cleared low, a low logic level on the corresponding GPIO
pin will set the corresponding INT_STS register bit.
GPIO Interrupts must also be enabled in GPIOx_INT_EN in the INT_EN
register.
Note:
Reserved
EEPROM Enable (EEPR_EN). The value of this field determines the
function of the external EEDIO and EECLK:
Please refer to
Note:
Reserved
GPIO Buffer Type 0-2 (GPIOBUFn). When set, the output buffer for the
corresponding GPIO signal is configured as a push/pull driver. When
cleared, the corresponding GPIO set configured as an open-drain driver.
Reserved
GPIO Direction 0-2 (GPDIRn). When set, enables the corresponding GPIO
as output. When cleared the GPIO is enabled as an input.

GPIO_CFG—General Purpose IO Configuration Register
This register configures the GPIO and LED functions.
Offset:
GPIO inputs must be active for greater than 40nS to be recognized
as interrupt inputs.
The host must not change the function of the EEDIO and EECLK
pins when an EEPROM read or write cycle is in progress. Do not
use reserved settings.
