Figure 14. Memory-to-Serial-Data-Register Cycle (VRAM Read Transfer)
This VRAM cycle is issued in any of three ways:
1.
2.
3.
Pixel operation instruction with the CST bit in DPYCTL set.
Horizontal blank reload cycle requested by the video-control logic with the VCE bit in DPYCTL cleared.
Video timeout due to SCOUNT match with the value in MLRNXT and the VCE and SSV bits in DPYCTL
cleared.
This cycle is indicated by TR/QE and SF low and CAS and WE high at the time RAS goes low. The timing of
the low-to-high transition of TR/QE is dependent upon the timing of SCLK when doing a midline reload cycle.
During the address portion of the cycle, the status on LAD0–LAD3 indicates either a video-initiated VRAM
memory-to-register transfer (status code = 0100) or a CPU-initiated VRAM memory-to-register transfer
(status code = 0101).
