Reserved - Unknown during read
Switch Status - Read Only
When SWTCH = ‘0’, Switch Status = ‘1’ means that RAM0
is in the video pipeline and RAM1 is accessible to the bus.
When SWTCH = ‘1’, Switch Status = ‘1’ means that RAM1
is in the video pipeline and RAM0 is accessible to the bus.
During active video, the switch does not occur until the
beginning of the next frame. When the video state
machine is disabled, the switch occurs almost
immediately.
Switch - Read/Write
Writing a Switch value to this bit selects which of these
conditions is present when SSTAT = ‘1’:
0 - RAM0 in video pipeline, RAM1 is accessible from bus
1 - RAM1 in video pipeline, RAM0 is accessible from bus.
