9.1 General
M68HC16 Z SERIES
USER’S MANUAL
This section is an overview of the queued serial module (QSM). Refer to the QSM Ref-
erence 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).
QSM. The QSM is present on the MC68HC16Z1, MC68CK16Z1, MC68CM16Z1,
MC68HC16Z2, and MC68HC16Z3 microcontrollers.
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 1 of 16 line selector.
A self-contained RAM queue allows up to sixteen serial transfers of eight to sixteen
bits each or continuous transmission of up to a 256-bit data stream without CPU16 in-
tervention. A special wrap-around mode supports continuous transmission/reception
of data.
