Introduction to Programming

The Status Model

Operation/Questionable Status Summary Register

•Bits 0 to 4 are built from the OSSER/QSSER and the OSSEM/QSSEM.

•A summary of the event register, the condition register and the enable mask is set in the status byte.

Operation/Questionable Slot Status

•The Operation/Questionable Slot Status consist of a condition and an event register.

•A "rising" bit in the condition register is copied to the event register.

•A "falling" bit in the condition register has no effect on the event register.

•Reading the condition register is non-destructive.

•Reading the event register is destructive.

•A summary of the event register, the condition register and the enable mask is set in the status byte.

Operation Slot Status Register

•Bit 0 is set if the laser is switched on.

•Bit 1 is set if the Coherence Control is switched on.

•Bit 3 is set if Power Meter zeroing or Tunable Laser module lambda zeroing is ongoing.

•Bit 4 is set if the attenuator output is enabled (shutter open).

•Bits 5 - 7 are set if the wavelength offset table is enabled (see page 68).

•All other bits are unused, and therefore set to 0.

Questionable Slot Status Register

•Bit 0 is set if excessive power is set by the user for any source module or if excessive averaging time is set for any Power Meter.

•Bit 1 is set if the last Power Meter zeroing failed.

•Bit 2 is set if temperature is out of range.

•Bit 3 is set if laser protection is switched on.
