Modes Of Operation; State Mode; Timing Mode - HP 16600A Series User Manual

Modes of Operation

The HP E2480A analysis probe can be used in State mode or Timing
mode. The following sections describe these operating modes.

State mode

In State mode, the logic analyzer uses clock store qualification to
capture address, data, and status information once during an
instruction or data cycle. This mode is set up by the State configuration
files. The State configuration files also automatically load the inverse
assembler.

Timing mode

In Timing mode, the logic analyzer samples the microcontroller pins
asynchronously, at a user-selected sampling rate. The Timing mode is
set up by the Timing configuration files.
State and Timing modes use different connectors on the analysis
probe. The Timing pins are direct connections to the microcontroller
signals. The State pins have active circuitry on the analysis probe.
State information is acquired three target system clock cycles after
the same information is captured in Timing mode.
