Transfer Speeds
ISA bus transfer rates are host-dependent and should be
determined by testing. For example, a Compaq computer
achieved 800 nanoseconds instantaneous sample-to-sample
timing to base memory using the REP INSW instruction. A
faster CPU will not increase the ISA bus speed. To optimize
throughput, disable all possible interrupts. For higher speed
continuous (non-stop) A/D sampling, consider using a parallel
port.

FIFO Data Format
A/D data is delivered as a stream from the FIFO memory. For
multichannel inputs, this means that data is multiplexed. For
example, for 4-channel inputs, the output channel sequence is
0, 1, 2, 3, 0, 1, . . . Some applications may need this data de-
multiplexed by software so that each channel’s data is placed
in its own separate buffer.
