3.4.3 CUSTOM_INT_PACKET (Read/Write)
This register is used to enable / disable GPIO status in the high data byte of the custom interrupt packet. See
Table 16, “Interrupt Packet Format,” on page 24 and Table 18, “Data Field of Customized Interrupt
Packet - Exar Vendor Specific,” on page 25.
CUSTOM_INT_PACKET[0]: GPIO1
• Logic 0 = Disable GPIO1 status in custom interrupt packet.
• Logic 1 = Enable GPIO1 status in custom interrupt packet.
CUSTOM_INT_PACKET[1]: GPIO2
• Logic 0 = Disable GPIO2 status in custom interrupt packet.
• Logic 1 = Enable GPIO2 status in custom interrupt packet.
CUSTOM_INT_PACKET[2]: Reserved
• This bit is reserved and should remain ’0’.
CUSTOM_INT_PACKET[3]: GPIO0
• Logic 0 = Disable GPIO0 status in custom interrupt packet.
• Logic 1 = Enable GPIO0 status in custom interrupt packet.
CUSTOM_INT_PACKET[4]: GPIO3
• Logic 0 = Disable GPIO3 status in custom interrupt packet.
• Logic 1 = Enable GPIO3 status in custom interrupt packet.
CUSTOM_INT_PACKET[5]: GPIO4
• Logic 0 = Disable GPIO4 status in custom interrupt packet.
• Logic 1 = Enable GPIO4 status in custom interrupt packet.
CUSTOM_INT_PACKET[6]: GPIO5
• Logic 0 = Disable GPIO5 status in custom interrupt packet.
• Logic 1 = Enable GPIO5 status in custom interrupt packet.
CUSTOM_INT_PACKET[7]: Reserved
This bit is reserved and should remain ’0’.
