Description
The mode bit selects the active operating mode of the ADC.
Set by the user to power up the ADC.
Cleared by the user to power down the ADC.
Set by the user to select an external reference.
Cleared by the user to use the internal reference.
The ADC clock divide bits (CK1, CK0) select the divide ratio for the PLL master clock (ADuC842/ADuC843) or the
external crystal (ADuC841) used to generate the ADC clock. To ensure correct ADC operation, the divider ratio
must be chosen to reduce the ADC clock to 8.38 MHz or lower. A typical ADC conversion requires 16 ADC clocks
plus the selected acquisition time.
The divider ratio is selected as follows:
CK1
0
0
1
1
1
2
The ADC acquisition select bits (AQ1, AQ0) select the time provided for the input track-and-hold amplifier to
acquire the input signal. An acquisition of three or more ADC clocks is recommended; clocks are as follows:
AQ1
0
0
1
1
1
4
The Timer 2 conversion bit (T2C) is set by the user to enable the Timer 2 overflow bit to be used as the ADC
conversion start trigger input.
The external trigger enable bit (EXC) is set by the user to allow the external Pin P3.5 (CONVST) to be used as the
active low convert start input. This input should be an active low pulse (minimum pulse width >100 ns) at the
required sample rate.
