PIC24EP64MC204-E/PT Microchip Technology, PIC24EP64MC204-E/PT Datasheet - Page 320

• Manufacturer Part Number: PIC24EP64MC204-E/PT
• Description: 16 Bit MCU, 64KB Flash, 8KB RAM, 60 MHz, 44 Pin, MCPWM,QEI, 3 OpAmp, 4 Comp, PTG
• Manufacturer: Microchip Technology

FIGURE 23-1:
This diagram depicts all of the available
ADC connection options to the four S&H
amplifiers, which are designated: CH0,
CH1, CH2, and CH3.
The ANx analog pins or op amp outputs
are connected to the CH0-CH3 amplifiers
through the multiplexers controlled by the
SFR
CH123Sx and CH123Nx.

Channels 1, 2 and 3 are not applicable for the 12-bit mode of operation.
These bits can be updated with Step commands from the PTG module. See
When ADDMAEN (ADxCON4<8>) = 1 enabling DMA, only ADCxBUF0 is used.
