Host interface

3.3.16

DL_DataConfirm (51h)

This command is sent by the ST7580 to provide a positive confirmation to

a DL_DataRequest (Section 3.3.15) previously requested by the external host.

The ConfirmData field has the same format as for PHY_DataConfirm (see Table 37).

3.3.17

DL_DataIndication (52h)

This command is sent by the ST7580 after a reception of a power line frame in compliance

with DL frame specification (Figure 3, i.e. with a CRC correct field) and it exports the

DL_Data indication service (Section 2.4). The command notification occurs if the modem is

set for receiving DL or SS frames at MIB object Modem Config 00h (Section 4.2.1), as in the

diagram flow in Figure 5.

The IndicationData fields are the same as for PHY_DataIndication (Table 39).

3.3.18

DL_SnifferIndication (5Ah)

This command is sent by the ST7580 after a reception of a power line frame in compliance

with DL frame specification (Figure 3, i.e. with a wrong CRC field) and it exports the

DL_Sniffer indication service (Section 2.4). The command notification occurs if the modem

is set for receiving DL or SS frames at MIB object Modem Config 00h (Section 4.2.1), as in

the diagram flow in Figure 5.

The IndicationData fields are the same as for PHY_DataIndication (Table 39). The payload

field presents the wrong CRC bytes also.
