Table 3-306 ADC_CFG_ADCPPB3CONFIG2 Register Field Descriptions

Bit	Field	Type	Reset	Description
15:14	COMPSEL	R/W	0h	Post Processing Block 3 Compare Source Select. This field determines whether ADCPPB3RESULT, ADCPPB3PSUM, or ADCPPB3SUM is used for the zero-crossing detect logic and threshold compare. 00 = ADCPPB3RESULT is used for compare logic 01 = ADCPPB3PSUM is used for compare logic 10 = ADCPPB3SUM is used for compare logic 11 = Reserved Note: when ADCPPB3PSUM is selected as the compare source and when a LIMIT match occurs [ADCPPB3LIMIT equals ADCPPB3COUNT] the ADCPPB3PSUM register will be cleared and the final sum will be loaded into ADCPPB3SUM. For this sample, the final sum, ADCPPB3SUM will be used for the compariosn instead of ADCPPB3PSUM.
13	RESERVED_2	R	0h	Reserved
12	OSINTSEL	R/W	0h	Post Processing Block 3 Interrupt Source Select. OSINT3 can be used to trigger an ADC interrupt [ADCINT1 through ADCINT4] via selection in the ADCINT1N2 or ADCINT3N4. This selection determines if a sync. event can trigger OSINT3 in addition to a PCOUNT = LIMIT event. 0 = OSINT3 will be generated from PCOUNT = LIMIT only 1 = OSTIN3 will be generated form PCOUNT = LIMIT or a sync. event. Note: If a SYNC event would cause an OSINT one cycle after OSINT would have been cause by PCOUNT = LIMIT match, then the second OSINT is ignored.
11	SWSYNC	R/W1TS	0h	PPB 3 software force sync. On a sync. event, all partial registers transfer to the final registers and are then reset. Note: In the case where the software force occurs at the same time that a new sample is added to the PSUM and the PSUM is being used for a high or low limit compare, then the comparison will not occur.
10	RESERVED_1	R	0h	Reserved
9:4	SYNCINSEL	R/W	0h	PPB 3 sync. input select. On a sync. event, all partial registers transfer to the final registers and are then reset.
3:0	SHIFT	R/W	0h	Post Processing Block 3 right shift. Defines the number of bits to right shift PSUM before loading into the final SUM. 0 : no right shift 1 : SUM = PSUM '' 1 2 : SUM = PSUM '' 2 ... 10 : SUM = PSUM '' 10 11 - 15 : Reserved
