TSC Module Status
The Auxiliary TSC module reports its status as part of the normal exchanges
with the main module.
The bit assignments are as follows.
Bits 0…7 are common to all types of auxiliary module, bits 8 to 15 are specific
to type.
The auxiliary module controls Bits 1…15, the main module sets bit 0.
If bit 0 is set, the remaining bits do not reflect the current auxiliary module
status.
If communication with an expansion module is lost, then the main module sets
a status bit to indicate an expansion bus fault. If communication are restored,
then normally the fault indication clears. However, if a configuration activity
has failed, then the fault indication remains set until a successful
reconfiguration is completed. Normally this reconfiguration is achieved by
downloading the configuration from the controller to the host main module.
