The following section lists the parameters.
3.3.1 Enable
This field defines how to execute the command:

Disable (0): disables the command. The command will not execute during the
normal polling sequence.

Continuous (1): executes the command during each scan of the command list
if the Poll Interval Time is set to zero (0). If the Poll Interval Time is set, the
command will be executed when the interval timer expires.

associated with the command changes. This value is only valid for WRITE
commands.

This field specifies the internal database register to be associated with the
command.

If the command is a read function, the data read from the slave device will be

If the command is a write function, the data written to the slave device will be
sourced from the address specified.
