conversion process.
after the ongoing conversion process is completed.
SLEEP or STOP) causes the ADC to be immediately disabled, even if a conversion is in progress. Once
the TMP1940CYAF exits the standby mode, the ADC restarts a conversion sequence when in a
continuous conversion mode, but remains inactive when in a single conversion mode.
The ADC supports the following four conversion modes:
The REPEAT and SCAN bits in the ADMOD1 select the conversion mode.
The ADC generates the INTAD interrupt and sets the EOCF bit in the ADMOD0 at the end of the
In continuous conversion modes, clearing the ADMOD0.REPEAT bit stops the conversion sequence
If the I2AD bit in the ADMOD1 is cleared, putting the TMP1940CYAF in any standby mode (IDLE,
Table 15.2 summarizes interrupt request generation in each of the conversion modes.
Fixed-Channel Single Conversion Mode
this mode, the ADC performs a single conversion on a single selected channel. When a conversion
is completed, the ADC sets the ADMOD0.EOCF bit, clears the ADMOD0.ADBF bit and generates
the INTAD interrupt.
Channel Scan Single Conversion Mode
this mode, the ADC performs a single conversion on each of a selected group of channels. When a
single conversion sequence is completed, the ADC sets the ADMOD0.EOCF bit, clears the
ADMOD0.ADBF bit and generates the INTAD interrupt.
Fixed-Channel Continuous Conversion Mode
this mode, the ADC repeatedly converts a single selected channel. When a conversion process is
completed, the ADC sets the ADMOD.EOCF bit. The ADMOD0.ADBF bit remains set.
cleared, the ADC generates an interrupt after each conversion. If the ITM0 bit is set, the ADC
generates an interrupt after every four conversions.
Channel Scan Continuous Conversion Mode
this mode, the ADC repeatedly converts the selected group of channels. When a single conversion
sequence is completed, the ADC sets the ADMOD0.EOCF bit and generates the INTAD interrupt.
The ADMOD0.ADBF bit remains set.
This mode is selected by programming the REPEAT and SCAN bits in the ADMOD0 to 00. In
This mode is selected by programming the REPEAT and SCAN bits in the ADMOD0 to 01. In
This mode is selected by programming the REPEAT and SCAN bits in the ADMOD0 to 10. In
The ITM0 bit in the ADMOD0 controls interrupt generation in this mode. If the ITM0 bit is
