Global Interrupt Status

The following table contains the interrupt status from the various sources to indicate which one caused

that last interrupt on the pin.

Port 1 enhanced serial LED

output enable

R/W

Enable the enhanced serial LED output

functionality for port 1 LED pins.

1: Enhanced serial LED outputs

0: Normal function

Port 0 enhanced serial LED

output enable

R/W
