R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-1 ADC Base Register: This register contains the base address of the user’s ADC Interrupt Service Rou-
tine jump table. This register, when read, contains the sum of the ADBASE register contents and the
encoded value of the PxRDY Status bits.
The encoder logic provides the bit number of the highest priority PxRDY bits where P0RDY is the
highest priority, and P5RDY is lowest priority.
Note: The encoding results are shifted left two bits so bits 1-0 of the result are always zero.
bit 0 Unimplemented: Read as ‘0’
Note: As an alternative to using the ADBASE Register, the ADCP0-5 ADC Pair Conversion Complete Interrupts
(Interrupts 37-42) can be used to invoke A to D conversion completion routines for individual ADC input
pairs. Refer to Section 16.9 “Individual Pair Interrupts”.
