4.3Channel Number and A/D Data — BASE+0 and BASE+1

These two bytes, BASE+0 and BASE+1, hold the result of A/D conversion data. The 12 bits of data from the A/D conversion are stored in BASE+1 bit 3 to bit 0 and BASE+0 bit 7 to bit 0. BASE+1 bit 7 to bit 4 hold the source A/D channel number.

AD11 ~ AD0 Result of A/D Conversion

AD0 is the least significant bit (LSB) of the A/D data, and AD11 is the most significant bit (MSB).

CH3 ~ CH0 A/D Channel Number

CH3 ~ CH0 hold the number of the A/D channel from which the data is received. CH3 is the MSB and CH0 is the LSB.

4.4 Software A/D Trigger — BASE+0

You can trigger an A/D conversion by software, the card’s on-board pacer or an external pulse. Bit 2 to bit 0 of register BASE+6 can select the trigger source (see page 39 and page 40 for the register layout of BASE+6 and programming information). If you select software triggering, a write to the register BASE+0 with any value will trigger an A/D conversion.
