byte. This analysis ignores any additional time consumed by the host processor.
The read all channels command consumes 740 microseconds maximum as follows:
140 us command response delay plus 15 more data bytes with 40 us data queue delay.
Notice that reading a block of eight channels is faster when using the read all channels
command rather than invoking the read channel data command eight times.
P ROCESSOR S PEED
Host processor speed is limited only by the bus interface circuitry on the sensor copro-
cessor board. The bus interface is designed to work with hosts operating at up to
16MHz. If you have a faster processor or a heavily loaded backplane, you may need to
insert wait states into your CPU's I/O cycles for reliable operation.
