Host interface

3.3.5

MIB_WriteConfirm (09h)

This command is sent by the ST7580 to acknowledge an MIB_WriteRequest (see

Section 3.3.4), if the request has been accepted and executed without errors.

3.3.6

MIB_ReadRequest (0Ch)

This command is used by the external host to read the current value of an MIB object.

The ST7580 checks the parameters for validation:



If the check is valid, the object is updated in the database and the ST7580 replies with

a MIB_ReadConfirm (Section 3.3.7).



If the check is not valid, the request is rejected and the ST7580 replies with

a MIB_ReadError (Table 12).
