MPEG Audio Source Decoder
SAA2500
host are done while keeping L3MODE HIGH. The devices with an L3 operational address differing from the issued one
must ignore these data transfers until the next operational address is issued. Only the device with an address equal to
the issued operational address performs the transfer.
The SAA2500 has the L3 operational address as shown in Table 13.
Table 13
L3 operational address.
Note
1.
The ‘Data Operation Mode’ bits DOM1 and DOM0 determine the mode in which the SAA2500 L3 interface will stay
until the next time an L3 operational address is issued (see Table 14).

Control bytes can be written to the SAA2500.
Data is transferred to or from the SAA2500 in so-called
data items. The items can be a readable or writeable type.
A data item transfer is initiated by writing the
corresponding control byte to the SAA2500 first. Next, the

item data itself is transferred, always as an integer number
of bytes.
The status of the SAA2500 can be read via L3. The
SAA2500 status flag L3RDY must be monitored before
transferring data item bytes to avoid transferring bytes
faster than the L3 interface of the SAA2500 can handle.
