DAC current control in Enhanced comparator user module of CY8C22345

Last Updated: March 27, 2011
Question: 

In enhanced comparator user module of CY8C22345, how do I control the DAC current (5 bit) if I select VDACL or VDACR as one of the input?

Answer: 

VDACL or VDACR are the voltage input coming from VDAC5.These values can be set by configuring registers VDAC50CR0 and VDAC51CR0.Writing to these registers, VDAC block can convert a 5-bit width digital code into analog voltage on VDACL and VDACR respectively within range from Ref Input/31 to Ref Input. Ref Input can be selected as Vdd or from regulated bandgap output by configuring register VDAC_TRIM.

For detailed information on VDAC please refer VDAC section on
