Register 4Eh GPIO Pin Polarity and Type
Reset settings = 0xFFFF
The GPIO Pin Polarity/Type register is read/write for selecting the polarity and type for Slot 12 I/O. This register
defines GPIO Input Polarity (0 = low, 1 = high active) when a GPIO pin is configured as an input. It defines GPIO
output type (0 = CMOS, 1 = OPEN-DRAIN) when a GPIO pin is configured as an output. The default value after
soft reset (FFFFh) is all pins active high. Non-implemented GPIO pins always return 1s.
Note: Register 4Eh is not effected by a cold or warm reset. (This is to avoid corrupting Sticky bits.)
Register 50h GPIO Pin Sticky
Reset settings = 0x0000
The GPIO Pin Sticky is a read/write register. It defines the GPIO input type (0 = Non-Sticky, 1 = Sticky) when a
GPIO pin (defined in slot 12 I/O) is configured as an input. Applies to Ring Detect, Delta Loop Current Sense,
GPIO_A, and GPIO_B bits.
GPIO inputs configured as Sticky are cleared only by writing a 0 to the corresponding bit of the GPIO Pin Status
Register 54h. The default value after cold register reset (0000h) is all pins Non-Sticky. Unimplemented GPIO pins
always return zeros. Sticky is defined as Edge sensitive; Non-Sticky is defined as Level sensitive.
Register 52h GPIO Pin Wake Up Mask
Reset settings = 0x0000
The GPIO Pin Wake-up is a read/write register that provides a mask for determining if an input GPIO change will
generate a wake-up or GPIO_INT (0 = No, 1 = Yes). When the AC-link is powered down, a wake-up event will
trigger the assertion of SDATA_IN. When AC-link is powered up, a wake-up event will appear as GPIO_INT = 1 on
bit 0 of input slot 12. Ring-detection wake-up can be enabled or disabled.
An AC-Link wake-up interrupt is defined as a 0 to 1 transition on SDATA_IN when the AC-link is powered down.
GPIO bits that have been programmed as Inputs, Sticky, and Pin Wake-up, upon transition (either high-to-low or
low-to-high) depending on pin polarity, will cause an AC-Link wake-up event, if the AC-Link was powered down.
The default value after cold register reset (0000h) defaults to all 0s specifying no wake-up event. Applies to Ring
Detect, Delta Loop Current Sense, GPIO_A, and GPIO_B bits. Non-implemented GPIO pins always return 0s.
