4.1.1 Video Options

The Video Control register is used to set up which video configuration is used and how to transition between the two video configurations.

Table 4-1 Video Control Register Configuration
LOOP CONFIGURATIONS (BIT 4) TOGGLE CONFIGURATIONS (BIT 5) CONFIGURATION POINTER (BIT 3) RESULT
VIDEO CONTROL REGISTER
0 0 0 Play config 1 once
0 0 1 Play config 2 once
0 1 0 Play (config 1, then config 2) once
0 1 1 Play (config 2, then config 1) once
1 0 0 Repeat config 1 continuously
1 0 1 Repeat config 2 continuously
1 1 0 Repeat (config 1, then config 2) continuously
1 1 1 Repeat (config 2, then config 1) continuously

If “Loop configurations” = 0, the end action is determined by “Auto-stop” (bit 2). The Auto-stop bit allows you to either fully turn off the video (1), or freeze on the last image in the video (0). If “Loop configurations” = 1, there is no end action because the video or videos will loop until stopped by command.
