At clock 0, the HCNT, VCNT and FRAME counters are 0x0. The pixel to display is a 5, which
translates to register base + 0x94, bit D0. At the next clock tick, the fastest running counter
(HCNT) has incremented, but VCNT and FRAME remain the same. Given the same pixel
value (5), bit position D1 is used as the value that is sent to the display.
