Video Port Control Registers
2-21 Video Port SPRU629
2.7.3 Video Port Interrupt Enable Register (VPIE)
The video port interrupt enable register (VPIE) enables sources of the video
port interrupt to the DSP. The VPIE is shown in Figure 2–5 and described in
Table 2–8.

Bit field † symval † Value Description
31–24 Reserved – 0 Reserved. The reserved bit location is always read as 0. A value
written to this field has no effect.
23 LFDB Long field detected on channel B interrupt enable bit.
DISABLE 0 Interrupt is disabled.
ENABLE 1 Interrupt is enabled.
22 SFDB Short field detected on channel B interrupt enable bit.
DISABLE 0 Interrupt is disabled.
ENABLE 1 Interrupt is enabled.
21 VINTB2 Channel B field 2 vertical interrupt enable bit.
DISABLE 0 Interrupt is disabled.
ENABLE 1 Interrupt is enabled.
