Theory of Operation and Clocking

Timing

For timing measurements, raw digital signals from the microcontroller are

presented to the logic analyzer through the timing connectors. The

acquisition clock is provided by the logic analyzer.

State

For state measurements, all signals are processed by active logic for time

alignment before they are routed to the state connectors. This allows the

logic analyzer to capture all information about a given cycle in one acquisition

state.

Some of the signals which assist the preprocessor in triggering and aligning

the source code are reconstructed from their reconfigured functions as chip

selects or general I/O. The preprocessor interface must be configured to

match the target system for this reconstruction function to work.

A qualified target system clock is used by the logic analyzer to acquire state

cycles.
