Manual Mode
The Trigger Counter is cleared when TSAMOD is written to define the Interleaved Mode, then it
simply rolls over.
The TSADCC features a manual mode allowing to control the state (open/close) of the four
switches.
Writing TSAMOD to “Manual Mode” automatically enables the ADC pins as analog inputs.The
switches positions are controlled through the
this mode, the “Sample and Hold Time” used is the one defined for the Touchscreen mode
(TSSHTIM).
To perform a measurement, the following sequence must be followed
• For Trigger Counter at 5:
1. Close the switches on the inputs Y
2. Convert Channel Y
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corre-
4. Set Trigger Counter to 6.
• For Trigger Counter at 6:
1. Close the switches on the inputs Y
2. Convert Channel Y
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corre-
4. Set Trigger Counter to 7.
• For Trigger Counter at 7:
1. Close the switches on the inputs Y
2. Convert Channel X
3. If Channel 4 to Channel 7 are enabled, convert Channels and store result in the corre-
4. Set Trigger Counter to 8.
• For Trigger Counter between 8 and (2
1. Increment Trigger Counter.
2. If Trigger Counter equals (2

1. Select the switch (switches) to close.
2. If SLEEP is set, wake up the ADC cell and wait for the Startup Time.
