2057 TO 2060 (0x809 TO 0x80C)—AUXILIARY ADC DATA REGISTERS
These registers hold the data generated by the 4-channel
auxiliary ADC. The ADCs have eight bits of precision and can
be extended to 12 bits if filtering is selected via Bits FIL [1:0] of
the auxiliary ADC and power control register. The SigmaDSP
program reads this data as a 1.11 format data-word with a range
of 0 to 1.0. This data-word is mapped to the 5.23 format
Rev. 0 | Page 35 of 52
parameter word with the four MSBs and 12 LSBs set to 0. A
full-scale code of 255 results in a value of 1.0. These registers
can be written to directly if the auxiliary ADC data registers
control port write mode (AACW) bit is set in the DSP core
control register.
