Bits 15:0 – ADCBASE[15:0] ADCISR Base Address bits

This register, when read, contains the base address of the user's ADC ISR jump table. The interrupt vector address is determined by the IRQVS[2:0] bits of the ADCCON1 register specifying the amount of left shift done to the ARDYx status bits in the ADCDSTAT1 register, prior to adding with ADCBASE register.

Interrupt vector address = Read value of ADCBASE

Read value of ADCBASE = Value written to ADCBASE + x << IRQVS[2:0], where ‘x’ is the smallest active analog input ID from the ADCDSTAT1 register (which has the highest priority).
