In one-shot mode and repeat mode, the ANEX0 and ANEX1 pins can be used as analog input pins. The
OPA1 and 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, but is stored into the AD00 register when the DUS bit in the AD0CON3
register is set to "1" (DMAC operating mode enabled).
Set the APS1 and APS0 bits in the AD0CON2 register to "00
MSS bit in the AD0CON3 register to "0" (multi-port sweep mode disabled).
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 and 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 AD0j register (j=0 to 7). A/D conversion rate varies depending on the response of
the external op-amp. The ANEX0 pin cannot be connected to the ANEX1 pin directly.
Set the APS1 and APS0 bits in the AD0CON2 register to "00
Figure 18.7 shows an example of an external op-amp connection.
