This mode provides a means for taking continuous conversions through all preprogrammed channels at the maximum rate of the card. There are two programmable options to this mode. One uses the external trigger or the software trigger as a gate for taking conversions. The process continues until the external trigger or the software trigger is reset. The other option allows the internal trigger counter to set the GO Bit and start the conversion process.
Conversions continue until the counter overflows stopping the process.
All conversions in Mode 2 are synchronized to the on-board 10 MHz clock. Pinout described below. PCs are used as controllers within vending machines, laboratory instruments, communications devices, and medical equipment, to name a few examples. By standardizing hardware and software around the broadly supported PC architecture, embedded system designers can substantially reduce development costs, risks, and time. This means faster time to market and hitting critical market windows with timely product introductions.
