 For Trigger Counter at 3:
1. Close the switches on the inputs Y
P
and Y
M
during the Sample and Hold Time.
2. Convert Channel Y
M
and store the result in TSADCC_CDR3.
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corresponding
TSADCC_CDRx and TSADCC_LCDR.
4. Set Trigger Counter to 4.
 For Trigger Counter at 4:
1. Close the switches on the inputs Y
P
and Y
M
during the Sample and Hold Time.
2. Convert Channel Y
P
, subtract TSADCC_CDR3 from the result and store the subtraction result in
TSADCC_CDR2 (and also in TSADCC_LCDR if PDCEN is enabled).
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corresponding
TSADCC_CDRx and TSADCC_LCDR.
4. Set Trigger Counter to 5.
 For Trigger Counter at 5:
1. Close the switches on the inputs Y
P
and Y
M
during the Sample and Hold Time
2. Convert Channel X
P
, subtract TSADCC_CDR3 from the result and store the subtraction result in
TSADCC_CDR3 (and also in TSADCC_LCDR if PDCEN is enabled).
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corresponding
TSADCC_CDRx and TSADCC_LCDR.
4. Set Trigger Counter to 6.
 For Trigger Counter between 6 and (2
TSFREQ+1
):
1. Increment Trigger Counter.
2. If Trigger Counter equals (2
TSFREQ+1
), then set Trigger Counter to 0.
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corresponding
TSADCC_CDRx and TSADCC_LCDR.
If the bit PRES in “TSADCC Mode Register” is enabled (measure both position and pressure), the sequences are
as follow:
 For Trigger Counter at 0:
1. Close the switches on the inputs X
P
and Y
M
during the Sample and Hold Time.
2. Convert Channel X
P
and store the result in TSADCC_Z1DR (and also in TSADCC_LCDR if PDCEN is
enabled).
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corresponding
TSADCC_CDRx and TSADCC_LCDR.
4. Set Trigger Counter to 1.
 For Trigger Counter at 1:
1. Close the switches on the inputs X
P
and Y
M
during the Sample and Hold Time.
2. Convert Channel Y
M
and store the result in TSADCC_Z2DR (and also in TSADCC_LCDR if PDCEN is
enabled).
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corresponding
TSADCC_CDRx and TSADCC_LCDR.
4. Set Trigger Counter to 2.
