Data in ADRRH and ADRRL should be read only when the A/D start flag (ADSF) in the A/D
start register (ADSR) is cleared to 0.
Changing the digital input signal at an adjacent pin during A/D conversion may adversely
affect conversion accuracy.
When A/D conversion is started after clearing module standby mode, wait for 10 ø clock
cycles before starting.
