Before requesting that the MVTX2601 updates the EEPROM device, the correct checksum needs to be calculated
and written into this checksum register. When the MVTX2601 boots from the EEPROM the checksum is calculated
and the value must be zero. If the checksum is not zeroed the MVTX2601 does not start and pin CHECKSUM_OK
is set to zero.
The checksum formula is: FF

Hold Time
Bit [0]

Bit [2:1]:
Hold time for LED signal
(Default= 00)
00 = 8 msec
01 = 16 msec
10 = 32 msec
11 = 64 msec
Bit [4:3]:
LED clock frequency
(Default 0)
For 100 MHz SCLK,
00 = 100 M/8 = 12.5 MHz
10 = 100 M/32 = 3.125 MHz 11 = 100 M/64 = 1.5625 MHz
For 125 MHz SCLK
00 = 125 M/64 = 1953 KHz 01 = 125 M/128 = 977 KHz
10 = 125 M/512 = 244 KHz 11 = 125 M/1024 = 122 KHz
01 = 100 M/16 = 6.25 MHz
