Register 275) and Host Top Field First bit (bit 4 in
Register 275) must be used by the host to specify the
display completely.
Indicates the status of the Rip Forward Display Single
Step Command as described in the following bit.
This bit should be set by the host after it has made the
decision on whether or not to display the current picture.
The L64105’s microcontroller waits for this bit to be set
before continuing with picture reconstruction in Rip
Forward Mode. This bit is only applicable when the Rip
Forward Mode Enable bit (bit 0 in this register) is set. The
microcontroller clears this bit when it reads it.
These bits indicate which frame store is being used for
displaying the current frame as shown in the following
table.
