cycle timing examples (continued)
This VRAM cycle (Figure 17) is performed when a pixel-write instruction is executed with the CST bit in DPYCTL
set. This cycle is indicated by TR/QE and WE low and SF and CAS high at the time RAS goes low. This cycle
does not require the use of SOE of the VRAM and does not affect the status of the serial I/O pins. During the
address portion of the cycle, the status on LAD0–LAD3 indicates that a CPU-initiated VRAM
register-to-memory transfer (status code = 0101) is being performed. Although PGMD and SIZE16 are ignored
on this cycle, they should be held at valid levels as shown.
