User’s Manual Pub. 0300246-01 Rev. C
Table 3-2 (Commands)
Command Value Description
Unlock 0×FFF0
This MUST be the first command issued after entering
Command Mode. If not, an error will be posted. Data
Words are ignored when the module enters command
mode.
The module does not need to detect a command
transition to Unlock. It simply waits for the Fixed
Words to be valid and Unlock command set. This
command is ignored if issued multiple times
(Response Code will be 0).
Once Command Mode is unlocked it remains unlocked
until it has been successfully configured and the Exit
command issued.
Clear
Command
0×FF00
Clears the command buffer to allow a command to be
re-issued. Since the module only knows a command is
issued when the Command word changes, the only
way to re-issue a command is to cause a transition.
This command gives the user a null command to do
that. The response is always 0. No other action is
taken with this command.
Load
Config
0×FFF1
Data Words 1-4 must contain valid channel
configuration data for all channels. See Data Words
table below.
Configuration will be validated. An error will be
posted for the first invalid channel configuration
found. If the configuration is invalid, the configuration
info in the Data Words may be modified but to re-issue
the Load Config, the Clear Command must be issued
first.
Exit 0×FF80
Delay 600 ms and then enter run state with
configuration. The delay begins after the response. If
configuration is not valid, the module will remain in
Command Mode until a valid configuration is entered.
1. Data Words 1-4 :
If the command requires valid data in the Data Words, they are validated
and a response is placed in the Response Code register (i.e. Word I:e.1).
See section 3.5.1 for a description of each response code.
The following table lists the possible configuration settings for each of
the 8 channels. Each Data Word contains two channel configurations.
See Table 3-1 for Data Word layout.
