Reset: 0xFF
Property: R/W

Bit 76543210 
 DACREF[7:0] 
Access R/WR/WR/WR/WR/WR/WR/WR/W 
Reset 11111111 

Bits 7:0 – DACREF[7:0] DACREF Data Value

These bits define the output voltage from the internal voltage divider. The DAC voltage reference depends on the DACREF value and the reference voltage selected in the VREF module, and is calculated as:

V DACREF = DACREF 256 × V REF
