EM78P350N  
8-Bit Microprocessor with OTP ROM  
6. Set the ADRUN bit to 1.  
7. Write “SLEP” instruction or Polling.  
8. Wait for wake-up or for ADRUN bit to be cleared (“0” value).  
9. Read the ADDATA or ADDATA1H and ADDATA1L conversion data registers. If  
ADC input channel changes at this time, the ADDATA, ADDATA1H, and  
ADDATA1L values can be cleared to ‘0’.  
10. Clear the interrupt flag bit (ADIF).  
11. For next conversion, go to Step 1 or Step 2 as required. At least 2 Tct is required  
before the next acquisition starts.  
NOTE  
In order to obtain accurate values, it is necessary to avoid any data transition on I/O  
pins during AD conversion.
