INTRSTATUS: Defines the interrupt status. There indicates a corresponding interrupt

while reading ‘1’ at a bit. Write ‘1’ to a bit will clear the corresponding

interrupt status. There is no effect while writing ‘0’ to any bit. Default

value is 0.

<0> Status of video loss from channel A

INTRMASK: Defines the interrupt masks. There represents that a corresponding interrupt

is masked while writing ‘1’ to a bit. AL700/701/710 will issue an “INTR”

request to an external micro-controller if there is at least one non-zero bit

in the INTRSTATUS register and its corresponding mask bit is 0. Default

value is 0.
