Questions answered in these manuals
What files are required to use the ADuC834 C-library?
Three files are required: the library itself (834keil.lib), the header file (lib834.h), and a modified C51s.lib library file.
How do you configure the primary ADC channel?
Use the AdcCfg function, passing parameters for ADC0CON, ADCICON, and SF registers to set reference, channel selection, coding mode, range, and update rate.
What is the workaround for the extended stack pointer PUSH/POP issue?
Push or pop data through the accumulator instead of using direct addressing, or use the Keil Compiler directive #pragma NOAREGS.
Which ADuC834 packages does this errata sheet apply to?
It applies to all ADuC834 packaged material branded as ADuC834BS or ADuC834BCP with a fourth line of F23.
What is the operating voltage range for the ADuC834?
The device operates from a 3V or 5V supply.
What is the power dissipation of the ADuC834 at 3V?
When operating from 3V, the power dissipation is below 10mW.
