Claim 0:
1. A driver module comprising:
an error flag interface block having a single terminal error flag input/output (EF I/O); and a control block coupled to the error flag interface block,
wherein the control block is coupled to enable the error flag interface block to respond to a signal indicative of a fault condition,
wherein the control block is coupled to inhibit the switching of an output of the driver module when in response to the detection of the fault condition external to the driver module by the error flag interface block, the fault condition indicated by an error flag state on the single terminal EF I/O, and
wherein the control block is coupled to control the error flag interface block to set an error flag state on the single terminal EF I/O in response to the detection of the fault condition local to the driver module.
