(b) Clock Variety
2. Bus matrix 2 of LCDDA and USB handles the earliest bus request first. If
1. Dynamic memory clock: Use HCLK clock
2. Static memory clock: Use HCLK or 1/2 HCLK
multiple bus requests are accepted simultaneously, they are handled according
to hardware priority.
Hardware priority is shown following
Hardware priority is shown following
LCDDA (high) C1 → USB (low)
Control clock is controlled in PLLCG circuit:
