converter circuit is power on. The EOC bit (bit6 of the
ADCR) is end of A/D conversion flag. Check this bit to
know when A/D conversion is completed. The START
bit of the ADCR is used to begin the conversion of the
A/D converter. Giving START bit a rising edge and fall-
ing edge means that the A/D conversion has started. In
order to ensure the A/D conversion is completed, the
START should remain at 0 until the EOC is cleared to
0 (end of A/D conversion).
The bit 7 of the ACSR is used for testing purposes only.
It can not be used by the users. The bit1 and bit0 of the
ACSR are used to select A/D clock sources.
