GPIO_CFGโ€”GENERAL PURPOSE IO CONFIGURATION REGISTER
This register configures the GPIO and LED functions.
1
PME Enable (PME_EN). When set, this bit enables the external PME signal.
This bit does not affect the PME interrupt (PME_INT).
R/W

0
Device Ready (READY). When set, this bit indicates that LAN9117 is ready
to be accessed. This register can be read when LAN9117 is in any power
management mode. Upon waking from any power management mode,
including power-up, the host processor can interrogate this field as an
indication when LAN9117 has stabilized and is fully alive. Reads and writes of
any other address are invalid until this bit is set.
Note:
With the exception of HW_CFG and PMT_CTRL, read access to
any internal resources is forbidden while the READY bit is cleared.

LED[3:1] enable (LEDx_EN). A โ€˜1โ€™ sets the associated pin as an LED output.
When cleared low, the pin functions as a GPIO signal.

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.
GPIO0 โ€“ bit 24
GPIO1 โ€“ bit 25
GPIO2 โ€“ bit 26
Note:
GPIO inputs must be active for greater than 40nS to be recognized
as interrupt inputs.

EEPROM Enable (EEPR_EN). The value of this field determines the function
of the external EEDIO and EECLK:
Please refer to Table 5-4 for the EEPROM Enable bit function definitions.
Note:
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.
Note:
Regardless of whether the internal or external PHY is selected,
RX_DV, TX_CLK and RX_CLK reflect the signals on the internal
PHY and the MAC always drives TX_EN.

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.
