Note: AD conversion accuracy may be low under the following conditions;
(1) When the VREF voltage is set to be lower than the VCC voltage, an analog circuit in this microcomputer is affected by noise.
The accuracy is lower than the case the VREF voltage is the same as VCC voltage.
(2) When the VREF voltage is 3.0 V or less at the low temperature, the AD conversion accuracy may be very lower than at room temperature.
When system is used at low temperature, that VREF is 3.0 V or more is recommended.
Ta = 25 °C
VCC = VREF = 2.7 to 5.5 V
AD conversion clock = f(XIN)/2
AD conversion clock = f(XIN)
VREF = 5.0 V
VREF = 3.0 V
