ANALOG DEVICES ADuC824: Errata Sheet (Rev 1.0 2000-12-01-)
The Analog Devices ADuC824 is a 16/24-bit ADC with an embedded Flash MCU. This errata sheet details specific issues found in all silicon branded as ADUC824BS, including known bugs and anomalies.
A critical issue identified involves indirect addressing modes where certain Special Function Registers (SFRs) cannot be read correctly using this method. The document provides a workaround involving the use of the accumulator register to bypass these restrictions for specific registers like ADCSTAT.
