Set FIFOSTAT to 1 to use the ALARM output to monitor
the data flow of the FIFO while in LUT streaming mode
or message mode. See the
LUT Streaming Mode and
Message Mode sections for more information on these
modes of operation and how to use the ALARM output
for FIFO flow control.
Set ADCMON to 1 to copy ADC conversion results into
the FIFO where it can be read out through the serial
interface. See the
ADC Monitoring Mode section for
more information on reading conversion results from
the FIFO. ADCMON and AVGMON cannot be active at
the same time.
Program PG_SET[1:0] to set the channel 1 and channel
2 current-sense amplifier gain (see Table 11c).
Program CKSEL[1:0] to set the conversion and acquisi-
tion timing clock modes (see Table 11d). See the
Internally Timed Acquisitions and Conversions section
for detailed descriptions of each clock mode.
Program ADCREF[1:0] to establish the source of the
ADC reference (see Table 11e). Program the
DACREF[1:0] to establish the source of the DAC refer-
ence (see Table 11f). See the
ADC and DAC
References section for more information on configuring
the data converter references.
Alarm Software Configuration Register (ALMSCFIG)
(Read/Write)
Configure the software alarm functions with bits D[11:0]
in the Alarm Software Configuration register (see Table
12). Bits D[15:12] are don’t-care bits.
Set A_AVG to 1 to enable the APC averaging and filter-
ing function for channel 1 and channel 2. The
APCSRC_ field in the SCFG register controls the source
of the sample.
