(2) When subclock is selected as system clock
The following wait times must be set in software during compare operation.
Wait time: Time of transition from operation stop mode to compare mode (2 instruction cycles)
Sets compare mode
(VREFEN, ADCEN, ADCCH1, ADCCH0)
(Set + compare)
Wait time (2 instruction cycles)
Reads ADCCMP
(Compare)
Wait time: Not necessary
(Compare)
Wait time: Not necessary
Reads ADCCMP
An example of a program in the compare mode when the subclock is selected is shown below.
COMPARE:
INITFLG
NOT VREFEN,NOT ADCEN,ADCCH1,ADCCH0 ; Starts comparing voltages on ADC
