Figure 52. ADC Description
Figure 53 shows the timing diagram of a complete conversion. For simplicity, the figure
depicts the waveforms in idealized form and do not provide precise timing information.
For ADC characteristics and timing parameters refer to the section “AC Characteristics”
of this datasheet.
Figure 53. Timing Diagram
Note:
Tsetup min, see the AC Parameter for A/D conversion.
Tconv = 11 clock ADC = 1sample and hold + 10-bit conversion
The user must ensure that Tsetup time between setting ADEN and the start of the first conversion.
ADC Converter
Operation
A start of single A/D conversion is triggered by setting bit ADSST (ADCON.3).
After completion of the A/D conversion, the ADSST bit is cleared by hardware.
The end-of-conversion flag ADEOC (ADCON.4) is set when the value of conversion is
available in ADDH and ADDL, it must be cleared by software. If the bit EADC (IEN1.1) is
set, an interrupt occur when flag ADEOC is set (See Figure 55). Clear this flag for re-
arming the interrupt.
Note:
Always leave Tsetup time before starting a conversion unless ADEN is permanently
high. In this case one should wait Tsetup only before the first conversion
