MC68336/376
USER’S MANUAL
This section is an overview of the queued serial module (QSM). Refer to the QSM
Reference Manual (QSMRM/AD) for complete information about the QSM.
The QSM contains two serial interfaces, the queued serial peripheral interface (QSPI)
and the serial communication interface (SCI). Figure 9-1 is a block diagram of the
QSM.
The QSPI provides peripheral expansion or interprocessor communication through a
full-duplex, synchronous, three-line bus. Four programmable peripheral chip-selects
can select up to sixteen peripheral devices by using an external one of sixteen line se-
lector. A self-contained RAM queue allows up to sixteen serial transfers of eight to six-
teen bits each or continuous transmission of up to a 256-bit data stream without
CPU32 intervention. A special wrap-around mode supports continuous transmission/
reception modes.
