Fault conditions are indicated on the FLT pin (HIGH during write mode and LOW during read mode). The fault condition
is coded and stored in Reg. 07 for monitoring purposes. The fault code is cleared on power up, on system reset and on
writing to Reg.09
The FLT output is an open collector to an external resistor of 5Kohms connected to +5V.
