INT/EOC output
Pin 19 outputs the status of the ADC conversion. When programmed as EOC, the output indicates the beginning
and the end of conversion. In the reset state, EOC is always high. During the sampling period (beginning after
the fourth falling edge of the I/O CLOCK sequence), EOC remains high until the internal sampling switch of the
converter is safely opened. The opening of the sampling switch occurs after the eighth, twelfth, or sixteenth I/O
CLOCK falling edge, depending on the data-length selection in the input data register. After the EOC signal goes
low, the analog input signal can be changed without affecting the conversion result.
The EOC signal goes high again after the conversion is completed and the conversion result is latched into the
output data register. The rising edge of EOC returns the converter to a reset state and a new I/O cycle begins.
On the rising edge of EOC, the first bit of the current conversion result is on DATA OUT when CS is low. When
CS is toggled between conversions, the first bit of the current conversion result occurs on DATA OUT at the
falling edge of CS.
When programmed as INT, the output indicates that the conversion is completed and the output data is ready
to be read. In the reset state, INT is always high. INT is high during the sampling period and until the conversion
is complete. After the conversion is finished and the output data is latched, INT goes low and remains low until
it is cleared by the host. When CS is held low, the MSB (or LSB) of the conversion result is presented on DATA
OUT on the falling edge of INT. A rising I/O CLOCK edge clears the interrupt.
