NOTES:
DAi register
When not using the D/A converter, set the DAiE bit (i = 0 or 1) to 0 (output disabled) and set the DAi register to 00h to
prevent current from flow ing into the R-2R resistor ladder to reduce unnecessary current consumption.
When not using the D/A converter, set the DAiE bit (i = 0 or 1) to 0 (output disabled) and set the DAi register to 00h to
prevent current from flow ing into the R-2R resistor ladder to reduce unnecessary current consumption.
1. The above diagram applies when the value of the DAi register is 2Ah.
2. VREF is not affected by the setting of the VCUT bit in the ADCON1 register.
