16.2 CONTROL REGISTERS

The ADC module has ten Control and Status registers. These registers are:

• ADxCON1: ADCx Control Register 1(1)

• ADxCON2: ADCx Control Register 2(1)

• ADxCON3: ADCx Control Register 3(1)

• ADxCON4: ADCx Control Register 4(1)

• ADxCHS123: ADCx Input Channel 1, 2, 3 Select Register(1)

• ADxCHS0: ADCx Input Channel 0 Select Register

• AD1CSSH: ADC1 Input Scan Select Register High

• ADxCSSL: ADCx Input Scan Select Register Low

• AD1PCFGH: ADC1 Port Configuration Register High

• ADxPCFGL: ADCx Port Configuration Register Low

The ADxCON1, ADxCON2 and ADxCON3 registers control the operation of the ADC module.

The ADxCON4 register sets up the number of conversion results stored in a DMA buffer for each

analog input in the Scatter/Gather mode. The ADxCHS123 and ADxCHS0 registers select the

input pins to be connected to the Sample/Hold amplifiers. The ADxPCFGH/L registers configure

the analog input pins as analog inputs or as digital I/O. The ADCSSH/L registers select inputs to

be sequentially scanned.
