FIFO THRS: FIFO threshold passed mask

0 = Disabled (default)

1 = Enabled FIFO_THRES interrupt

TTX: Teletext data available mask

0 = Disabled (default)

1 = Enabled TTX available interrupt

WSS: WSS data available mask

0 = Disabled (default)

1 = Enabled WSS available interrupt

VPS: VPS data available mask

0 = Disabled (default)

1 = Enabled VPS available interrupt

VITC: VITC data available mask

0 = Disabled (default)

1 = Enabled VITC available interrupt

CCF2: CC field 2 data available mask

0 = Disabled (default)

1 = Enabled CC_field 2 available interrupt

CCF1: CC field 1 data available mask

0 = Disabled (default)

1 = Enabled CC_field 1 available interrupt

Line: Line number interrupt mask

0 = Disabled (default)

1 = Enabled Line_INT interrupt

The host interrupt mask 0 and 1 registers can be used by the external processor to mask unnecessary interrupt sources for the interrupt status 0 and 1 register bits, and for the external interrupt terminal. The external interrupt is generated from all nonmasked interrupt flags.
