Interrupt polarity A
YUV enable:
0 = YUV pins are high-impedance
1 = YUV pins are active if other conditions are met (default)
Interrupt A (read-only):
0 = Interrupt A is not active on the external pin (default)
1 = Interrupt A is active on the external pin
Interrupt polarity A:
0 = Interrupt A is active low (default)
1 = Interrupt A is active high
Note that when the interrupt A is configured as active low, the terminal is driven low when active and high-impedance
when inactive (open drain). Conversely, when the terminal is configured as active high, it is driven high-impedance
when active and driven low when inactive.

The configuration RAM data is provided to initialize the VDP with initial constants. The configuration RAM is 512 bytes
total organized as 32 different configurations of 16 bytes each. The first 26 configurations are defined for the current
VBI standards. An additional 2 configurations can be used as a custom programmed mode for unique standards.
Address C3h is used to read or write to the RAM. The RAM internal address counter is automatically incremented
with each transaction. Addresses C5h and C4h make up a 9-bit address to load the internal address counter with a
specific start address. This can be used to write a subset of the RAM for only those standards of interest. Registers

–
FBh must all be programmed with FFh, before writing or reading the configuration RAM. Full field mode (CFh)
must be disabled as well.
The suggested RAM contents are shown below. All values are hexadecimal.
