NOTES ON LOADING AND READING THE RANGE CONTROL ACCUMULATOR:
Master Bus -> Holding Register -> Accumulator -> Holding Register
The accumulator is 17 bits. The lower 16 bits are loaded from the micro-processor interface master register into a holding register.
The MSB of the input holding register is always zero. The accumulator is loaded from the holding register. When the accumulator is
read, the most significant 16 accumulator bits are returned (the LSB of the accumulator is not read).
Range Control bit weights are listed in Table 85 in the back
of the data sheet.
