YUV enable (VDPOE):
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.
Interrupt configuration register A is used to configure the polarity of the external interrupt terminal. When
interrupt A is configured as active low, the terminal is driven low when active and high-impedance when
inactive (open collector). Conversely, when the terminal is configured as active high, it is driven high 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 organized as 32 different configurations of 16 bytes each. The first 12 configurations are defined
for the current VBI standards. An additional 2 configurations can be used as a custom programmed mode for
unique standards like Gemstar.
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 D0hFBh 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.
