Error Handling
Section 8-2
Host Link Master
For the Host Link master protocol, any error with communication can be read
from the status represented by the HLM_STATUS parameter. In the process
of sending a Host Link command and receiving a response several problems
may occur:
1.
The slave detects an error within the command and will send a corre-
sponding end code indication.
2.
The slave cannot decode the command header code and sends a IC re-
sponse.
3.
The master detects an error within the response. The corresponding end
code will be defined in the status.
