TLV2544/TLV2548 conversion modes (continued)
Table 4. TLV2544/TLV2548 Conversion Mode
CONVERSION
MODE
CFR
D(6,5)
SAMPLING
TYPE
OPERATION
One shot
00
Normal
Single conversion from a selected channel
CS or FS to start select/sampling/conversion/read
One INT or EOC generated after each conversion
Host must serve INT by selecting channel, and converting and reading the previous output.
Extended
Single conversion from a selected channel
CS to select/read
CSTART to start sampling and conversion
One INT or EOC generated after each conversion
Host must serve INT by selecting next channel and reading the previous output.
Repeat
01
Normal
Repeated conversions from a selected channel
CS or FS to start sampling/conversion
One INT generated after FIFO is filled up to the threshold
Host must serve INT by either 1) (FIFO read) reading out all of the FIFO contents up to the
threshold, then repeat conversions from the same selected channel or 2) writing another
command(s) to change the conversion mode. If the FIFO is not read when INT is served, it is
cleared.
Extended
Same as normal sampling except CSTART starts each sampling and conversion when CS is
high.
Sweep
10
Normal
One conversion per channel from a sequence of channels
CS or FS to start sampling/conversion
One INT generated after FIFO is filled up to the threshold
Host must serve INT by (FIFO read) reading out all of the FIFO contents up to the threshold, then
write another command(s) to change the conversion mode.
Extended
Same as normal sampling except CSTART starts each sampling and conversion when CS is
high.
Repeat sweep
11
Normal
Repeated conversions from a sequence of channels
CS or FS to start sampling/conversion
One INT generated after FIFO is filled up to the threshold
Host must serve INT by either 1) (FIFO read) reading out all of the FIFO contents up to the
threshold, then repeat conversions from the same selected channel or 2) writing another
command(s) to change the conversion mode. If the FIFO is not read when INT is served it is
cleared.
Extended
Same as normal sampling except CSTART starts each sampling and conversion when CS is
high.
NOTES:
1. Programming the EOC/INT pin as the EOC signal works for mode 00 only. The other three modes automatically generate an INT
signal irrespective of how EOC/INT is programmed.
2. Extended. Sampling mode using CSTART as the trigger only works when internal reference is selected for conversion modes 01,
10, and 11.
3. When using CSTART to sample in extended mode, the falling edge of the next CSTART trigger should occur no more than 2.5
s
after the falling CS edge (or falling FS edge if FS is active) of the channel select cycle. This is to prevent an ongoing conversion from
being canceled.
