8.1.3 DF1 Ports - Error/Status Data
The serial port (DF1 Master/Slave) Error and Status Data areas are discussed in
this section. The Error Status Pointer value is configured in the CFG file within
each of the individual [DF1 PORT X] sections.
The data area is initialized with zeros whenever the module is initialized. This
occurs during a cold-start (power-on), reset (reset push-button pressed) or a
warm-boot operation (commanded or loading of new configuration).
