Control
• Bit 0 of this register is the
Go
bit:
• Setting this bit to 1 causes the CVI IP core start data
output on the next video frame boundary.
• Bits 3, 2, and 1 of the
Control
register are the interrupt
enables:
• Setting bit 1 to 1, enables the status update interrupt.
• Setting bit 2 to 1, enables the stable video interrupt.
• Setting bit 3 to 1, enables the synchronization outputs
