A/D0 and A/D1 start simultaneously when the PST bit in the AD0CON2 register is set to "1" (two-circuit
simultaneous start).
Do not set the PST bit to "1" while either A/D0 or A/D1 is performing an A/D conversion, or if the TRG bit
is set "1" (external trigger).
Do not set the ADST bit to "1" (A/D conversion started) when using the PST bit.
When the ADS bit in the AD0CON2 register is set to "1" (channel replacement enabled), channels of the
A/D0 can be replaced with channels of the A/D1 and vice versa.
Voltage applied to the ANj (j = 0 to 7) pin is converted to digital code in the A/D1 and the conversion result
is stored into the AD1j register. Voltage applied to the AN0j, AN2j or AN15j pin is converted to digital code
in the A/D0 and the conversion results are stored into the AD0j register.
To set the ADS bit to "1", set the MD1 to MD0 bits in the AD0CON0 register to "00

OPA1 to OPA0 bits in the AD0CON1 register to "00
both AD0CON0 register and AD1CON0 register, and to both AD0CON1 register and AD1CON1 register.
