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.
