In simultaneous sample sweep mode, analog voltages applied to the selected pins are converted one-by-
one to a digital code. The input voltages of AN0 and AN1 are sampled simultaneously using two circuits
of sample and hold circuit. Table 15.8 shows the simultaneous sample sweep mode specifications. Fig-
ure 15.16 shows the operation example in simultaneous sample sweep mode. Figure 15.17 shows
ADCON0 to ADCON2 registers and Figure 15.18 shows ADTRGCON registers in simultaneous sample
sweep mode. Table 15.9 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 soft-
ware trigger, AD
underflow or A/D trigger mode of Timer B.

The SCAN1 to SCAN0 bits in the ADCON1 register and ADGSEL1 to
ADGSEL0 bits in the ADCON2 register select pins. Analog voltage applied
to the selected pins is converted one-by-one to a digital code. At this time,
