HT46R068B/HT46R069B
Enhanced A/D Type 8-bit OTP MCU
normal run, the ADC module can be turned off by setting ADONB=1 in ACSR. Once the ADC
module is turned off, the ADC module and analog channel have no power consumption no matter
what voltage level is on analog input. If the I/O lines is selected as an I/O function and the analog
input pin voltage is not equal to VDD or VSS, there user may have to take care IDD/ISTB current
consumed by the pin-shared logic input function no matter the ADC module is on or off. If the
ADC module is turned off, then all the ADC pin-shared I/O pins will be setup as normal I/Os.
