PRODUCT SPECIFICATION
Figure 5-3 : Timing diagram single step conversion.
ADCRUN=0, and conversion is started at first posedge ADCCLK after CSTARTN
has gone high. A pulse is generated on ADC_EOF when the converted value is
available on the ADCDATA bus. Conversion time t
t
bit conversion is shown. Minimum width of a CSTARTN pulse is 1 clock cycle. If a
new CSTARTN pulse comes before previous conversion has finished, the previous
conversion will be aborted.
Figure 5-4 : Timing diagram continuous mode conversion.
ADCRUN=1, and CSTARTN is ignored. Cycle time t
conversion. t
figure is showing 10 bit conversions.
