Enable external start of conversion by STADC
0 = Conversion can be started by software only (by setting ADCS)
1 = Conversion can be started by software or externally (by a rising edge on STADC)
ADC interrupt flag: this flag is set when an A/D conversion result is ready to be read. An interrupt is
invoked if it is enabled. The flag may be cleared by the interrupt service routine. While this flag is set,
the ADC cannot start a new conversion. ADCI cannot be set by software.
ADC start and status: setting this bit starts an A/D conversion. It may be set by software or by the
external signal STADC. The ADC logic ensures that this signal is HIGH while the ADC is busy. On
completion of the conversion, ADCS is reset immediately after the interrupt flag has been set. ADCS
cannot be reset by software. A new conversion may not be started while either ADCS or ADCI is high.

Analogue input select: this binary coded address selects one of the
eight analogue port bits of P5 to be input to the converter. It can only
be changed when ADCI and ADCS are both LOW.

If ADCI is cleared by software while ADCS is set at the same time, a new A/D conversion with the
same channel number may be started.
But it is recommended to reset ADCI
before
ADCS is set.
