SLIPE:
The SLIPE bit position is an interrupt enable that when set, enables the INTB
output to assert low when a slip occurs. When the block is reset the SLIPE
bit position is cleared and interrupt generation is disabled.
SLIPD:
The SLIPD bit indicates the direction of the last slip. If the SLIPD bit is a
logic 1 then the last slip was due to the frame buffer becoming full; a frame
was deleted. If the SLIPD bit is a logic 0 then the last slip was due to the
frame buffer becoming empty; a frame was duplicated.
SLIPI:
The SLIPI bit is set if a slip occurred since the last read of this register. The
SLIPI bit is cleared upon reading this register.
