ANALOG DEVICES ADuC832: Errata Sheet (Rev B1 2002-11-01-)

About this manual

The Analog Devices ADuC832 Errata Sheet (Rev B1) details specific known defects and anomalies associated with the ADuC832 MicroConverter device. The document covers three primary issues: variations in the number of ADC clocks required during conversion at low voltages, unexpected output spikes when clearing DAC bits in buffered mode, and incorrect operation of PUSH/POP instructions for direct addresses less than 80H when using an extended stack pointer.

Frequently asked questions

Does the ADC clock issue affect performance?

No, the document states that this issue does not affect the performance of the ADC.

How many ADC clocks are required for a conversion in pipelined mode at voltages below 3.5V?

The number of ADC clocks can vary between 15 and 16 ADC clocks.

What is the workaround to force the output of DAC1 or DAC0 to OV when a spike occurs?

Write 0000H to the corresponding DAC data registers.

How much internal XRAM does the extended stack pointer allow the stack to extend into?

The stack can extend into the 2 KBytes of internal XRAM.
