Limits

Notes 1: When the A/D converter is used, IADD is added to IDD (supply current).

2: As for the error from the ideal value in the comparator mode, when the contents of the comparator register is n, the logic value of the comparison

voltage Vref which is generated by the built-in DA converter can be obtained by the following formula.

Logic value of comparison voltage Vref

Vref =

✕ n

n = Value of register AD (n = 0 to 255)
