Notes 1: When the A/D converter is used, the IADD is included to IDD.
2: As for the error from the logic 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
VDD
Vref = ₂₅₆ ✕ n
n = Value of register AD (n = 0 to 255)
