11.1 General
MC68HC16Y3/916Y3
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. Refer to D.7
Queued Serial Module for a QSM address map and register bit and field definitions.
The QSM contains two serial interfaces, the queued serial peripheral interface (QSPI)
and the serial communication interface (SCI). On the MC68HC16Y3/916Y3, only the
QSPI is used; the SCI is not available. Instead, the multichannel communications in-
terface (MCCI) is used to provide two channels of asynchronous communication.
Refer to SECTION 12 MULTICHANNEL COMMUNICATION INTERFACE for more
information.
Figure 11-1 is a block diagram of the QSM.
