3.22.29 Interrupt Configuration Register B

Address 1Eh

7 6 5 4 3 2 1 0

Reserved Interrupt polarity B

Interrupt polarity B:

0 = Interrupt B is active low (default).

1 = Interrupt B is active high.

Interrupt polarity B must be same as interrupt polarity A bit at bit 0 of the interrupt configuration register A at

address C2h.

Interrupt configuration register B is used to configure the polarity of interrupt B on the external interrupt pin.

When the interrupt B is configured for active low, the pin is driven low when active and high-impedance when

inactive (open-collector). Conversely, when the interrupt B is configured for active high, it is driven

high-impedance for active and driven low for inactive.

3.22.30 Video Standard Register

Address 28h

7 6 5 4 3 2 1 0

Reserved Video standard

Video standard:

0000 = Autoswitch mode (default)

0001 = Reserved

0010 = (M) NTSC ITU−R BT.601

0011 = Reserved

0100 = (B, G, H, I, N) PAL ITU−R BT.601

0101 = Reserved

0110 = (M) PAL ITU−R BT.601

0111 = Reserved

1000 = (Combination-N) ITU−R BT.601

1001 = Reserved

1010 = NTSC 4.43 ITU−R BT.601

1011 = Reserved

1100 = Reserved

With the autoswitch code running, the user can force the device to operate in a particular video standard mode

and sample rate by writing the appropriate value into this register.

3.22.31 MSB of Device ID Register

Address 80h

7 6 5 4 3 2 1 0

MSB of device ID

This register identifies the MSB of the device ID. Value = 0x51.

3.22.32 LSB of Device ID Register

Address 81h

7 6 5 4 3 2 1 0

LSB of device ID

This register identifies the LSB of the device ID. Value = 0x50.
