14.10.1 Burst Mode

When MODE = 01, the scanner is in Burst mode. In Burst mode, CPU operation is stalled beginning with the operation after the one that sets the SCANGO bit, and the scan begins, using the instruction clock to execute. The CPU is held in its current state until the scan stops. Note that because the CPU is not executing instructions, the SCANGO bit cannot be cleared in software, so the CPU will remain stalled until one of the hardware end-conditions occurs. Burst mode has the highest throughput for the scanner, but has the cost of stalling other execution while it occurs.
