CHRONTEL
Bits 7-4 (RNUM#) of the FR register contain the revision number of the CH5001 device. These bits are read only.
When using ELFA=1, if 30 Hz frame rate is desired a 30MHz crystal should be used, and the 24MHz MCLK control
(MCE=0) should be selected. All frame rates will be scaled by the value of 30/24.
Horizontal Start Register
Register HS determines the number of pixels between the leading edge of H Sync and the first active pixel to be
output on the Y[7:0] and C[7:0] pins. The number is in units of pixels; the range is from 0 to 63 CLKOUT and must
be limited to 38 when ELFA=1. When M[2:0] = 4 or 5, this register is ignored and the timing below is followed
assuming 16-bit output mode. Values are doubled for 8-bit output mode
