1. Ts = pixel clock period = memory clock, [memory clock]/2, [memory clock]/3, [me mory c lock ]/4 (see REG[ 19h] bi ts [1:0] )
2. t1min = t4min - 14Ts
3. t4min = [((REG[04h] bits [6:0])+1)*8 + ((REG[05h] bits [4:0]) + 1)*8] + 33 Ts
4. t5min = [(((REG[04h] bits [6:0])+1)*8 + ((REG[05h] bits [4:0]) + 1)*8)-1] Ts
5. t6min = [((REG[05h] bits [4:0]) + 1)*8 - 27] Ts
6. t9min = [((REG[05h] bits [4:0]) + 1)*8 - 18] Ts
