Functional problems detail 3.1 ADC.1: Single Step mode multi channel boundary interrupt Introduction: The ADC on the P89LPC9331 is an Analog to Digital converter with 8 bits of resolution. The ADC has features such as a Single Step mode where the ADC will step through the selected channels on each ADC start condition. Problem: When the ADC is in Single Step mode with more than 1 channel selected, and a boundary interrupt occurs to any of the lower selected channel-bits, a write to the ADMODA register to clear the BNDI bit before all the selected channels are converted will reset the channel selection counter and the ADC will go back and wait at the lowest selected channel for the next conversion. This applies to both ADC0 and ADC1 on the P89LPC9331. Work-around: 1. Clear the lower channel bits including the boundary interrupted channel in ADCINS register before the next start request. 2. Use the default boundary channel, not clear BNDI bit until all channels are converted. 4. AC/DC deviations detail No known errata ES_P89LPC9331_2 All information provided in this document is subject to legal disclaimers. Errata sheet Rev. 02 — 8 March 2010 © NXP B.V. 2010.
