Introduction
The registers in this section are only required when using the GPIO port to input digital video signal. These registers
are included to enable the GPIO port to seamlessly connect to digital video cameras.
Digital Video Signal Interface Format
Memory Mapped Location 0x0FC – (DVSIF)
Upon reset, it is initialized to 0x000.
