When using MSB Logic, the analog input channels can be accessed via the Y registers. Y20 ~ Y27 correspond to channels 0 ~ 7 respectively. These channels are 10-bit, so the value stored ranges from 0 to 1023.
Registers Y30 ~ Y37 store a scaling factor for channels 0 ~ 7 respectively. The value can range between 0 and 10,000. The default is 10,000. The scaled result is stored in registers Y40 ~ Y47 for channels 0 ~ 7 respectively.
