GDATx Register: EEPROM Data for the Gamma Channels
This is an example of how the bits are arranged for a typical GDATx memory location. GDATx has 10 bits that are
arranged in two consecutive bytes. The following example shows the arrangement for GM1 GDAT1 (58h–59h). This
arrangement is applicable for all the EEPROM data for all gamma channels.

DS3514 Mode (MODE[1:0]):
00 = S0/S1 pins are used to select the desired bank (A–D) (default).
01 = SOFT S0/S1 (bits) are used to select the desired bank (A–D).
1X = Latch A is used to control the DACs.
