26.4.2.2 Decimation Filter Module Status Register (DECFILTER_MSR)
29
TORE
Triggered Output Result Enable. The TORE bit enables an input trigger signal to force the
decimation filter to send the next result of the filter back to the master block. For more details,
see
Section 26.5.4.2, Triggered output result description .
1 Output buffer update using an external signal is enabled
0 Output buffer update using an external signal is disabled
Note: TORE must only be asserted when PSI is selected as output (normal or PSI output mixed
modes).TORE must not be asserted with the filter bypassed (FTYPE = 00).
30–31
TMODE[1:0]
Trigger Mode. The TMODE field selects the way the trigger signal controls the output result
sampling function enabled by the TORE bit, as shown in
Table 26-10 .
Note: The TMODE definition replaces, and is upward compatible with, the TRFE bit definition
found in previous versions of the Decimation Filter.
