Decimation Filter
28.2.2.9 Decimation Filter Interface Enhanced Debug Input Data Register
(DECFILT_x_EDID)
The Enhanced Debug Input Data Register provides read-only access to the sample data received by the
Decimation Filter when the input is selected from an eQADC module (DECFILT_x_MCR[IO_SEL[1]]
=0), allowing the monitoring of input data from an eQADC. See Section 28.3.15, Enhanced Debug
Monitor Description for more details, and see Section 28.3.12.1.2, Input Buffer Enhanced Debug Monitor
Interrupt and Section 28.3.12.1.4, Input Buffer Enhanced Debug Monitor DMA Request for more
information on interrupt and DMA requests associated with the Enhanced Debug Monitor. Writes to this
register have no effect.

Description
0–15 Reserved
16–31 Conversion Sample Data—The SAMP_DATA[15:0] bit field carries the data that was loaded into the Decimation
SAMP_DATA Filter input buffer to be processed by the FIR/IIR sub-block. This value is only updated by input data received
from an eQADC (DECFILT_x_MCR[IO_SEL[1]] = 0), and the Enhanced Debug Monitor is enabled
(DECFILT_x_MCR[EDME] = 1).
