Read DAC A data. The device expects an S
followed by an address word with R/W = 1.
Read DAC B data. The device expects an S
followed by an address word with R/W = 1.
Read DAC C data. The device expects an S
followed by an address word with R/W = 1.
Read DAC D data. The device expects an S
followed by an address word with R/W = 1.
