3.3.3

BIO_ResetIndication (3Eh)

This command is sent by the ST7580 to notify the host about a reset or a power-on event.

3.3.4

MIB_WriteRequest (08h)

This command is used by the external host to access an object of the MIB.

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_WriteConfirm (Section 3.3.5).



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

a MIB_WriteError (Table 12).
