In one-shot mode and repeat mode, the ANEX0 and ANEX1 pins can be used as analog input pins. The
OPA1 to OPA0 bits in the AD0CON1 register select which pins to use as analog input pins. An A/D
conversion result for the ANEX0 pin is stored into the AD00 register. The result for the ANEX1 pin is
stored into the AD01 register.
In external op-amp connection mode, multiple analog voltage can be amplified by one external op-amp
using extended analog input pins ANEX0 and ANEX1.
When the OPA1 to OPA0 bits in the AD0CON1 register are set to "11
voltage applied to the AN
op-amp and apply it to ANEX1.
Analog voltage applied to ANEX1 is converted to a digital code and the A/D conversion result is stored
into the corresponding ADij register (i=0, 1; j=0 to 7). A/D conversion rate varies depending on the
response of the external op-amp. Do not connect the ANEX0 pin to the ANEX1 pin directly.
Figure 17.8 shows an example of an external op-amp connection.
