1. AN
In simultaneous sample sweep mode, analog voltages applied to the selected pins are converted one-by-
one to a digital code. At this time, the input voltage of AN
circuits of sample and hold circuit. Table 14.1.6.1 shows the simultaneous sample sweep mode specifica-
tions. Figure 14.1.6.1 shows the operation example in simultaneous sample sweep mode. Figure
14.1.6.2 shows ADCON0 to ADCON2 registers and Figure 14.1.6.3 shows ADTRGCON registers in
simultaneous sample sweep mode. Table 14.1.6.2 shows the trigger select bit setting in simultaneous
sample sweep mode. In simultaneous sample sweep mode, Timer B0 underflow can be selected as a
trigger by combining software trigger, AD
frequency setting counter underflow or A/D trigger mode of Timer B.
