2.4.4 Video Port Interrupt Status Register (VPIS)

The video port interrupt status register (VPIS) displays the status of video port interrupts to the DSP. The interrupt is only sent to the DSP if the corresponding enable bit in VPIE is set. All VPIS bits are cleared by writing a 1, writing a 0 has no effect.

The video port interrupt status register (VPIS) is shown in Figure 2-4and described in Table 2-6.
