What are the Python code steps to enable INT1 and 2 to be external level detecting Inputs?
53 = x"00" disables Int as output and makes Int2 and Int1 Input Level Detectors
54 = x"30" enables both Int 2 and Int1 as nonlatched Interrupts
Anything else required?

Take the INT1 pin as an input for example, below are the steps:
In normal stage, Vsync is low and the FIFO frame header is 0x84 (fh_ext<1:0> = 00). Once Vsync is issued, the related FIFO frame header will be 0x85 (fh_ext<1:0> = 01).
