Analog-to-Digital
Converter (ADC)
This section describes the on-chip 10 bit analog-to-digital converter of the AT8xEB5114.
Six ADC channels are available for sampling of the external sources AIN0 to AIN5. An
analog multiplexer allows the single ADC converter to select one from the 6 ADC chan-
nels as ADC input voltage (ADCIN). ADCIN is converted by the 10 bit-cascaded
potentiometric ADC.
8 to 10 bits resolution can only be reached while using an external voltage reference.
For the precision conversion, set bits PSIDLE and ADSST in ADCON register to start
the conversion. The chip is in a pseudo-idle mode, the CPU doesn’t run but the periph-
erals are always running. This mode allows digital noise to be lower, to ensure precise
conversion.
For accurate conversion, set bits QUIETM and ADSST in ADCON register to start the
conversion. The chip is in a quiet mode, the AD is the only peripheral running. This
mode allows digital noise to be as low as possible, to ensure high precision conversion.
For these modes it is necessary to work with end of conversion interrupt, which is the
only way to wake up the chip.
If another interrupt occurs during the precision conversion, it will be treated only after
this conversion is ended.
