5 Queued Serial Module
The QSM contains two serial interfaces: the queued serial peripheral interface (QSPI) and the serial
communication interface (SCI). Figure 17 shows the QSM block diagram.

5.1 Overview
The QSPI provides peripheral expansion or interprocessor communication through a full-duplex, syn-
chronous, three-line bus: data in, data out, and a serial clock. Four programmable peripheral chip-select
pins provide addressability for up to 16 peripheral devices. A self-contained RAM queue allows up to
16 serial transfers of 8 to 16 bits each, or transmission of a 256-bit data stream without CPU interven-
tion. A special wraparound mode supports continuous sampling of a serial peripheral, with automatic
QSPI RAM updating, which makes the interface to A/D converters more efficient.
The SCI provides a standard non-return to zero (NRZ) mark/space format. It operates in either full- or
half-duplex mode. There are separate transmitter and receiver enable bits and dual data buffers. A
modulus-type baud rate generator provides rates from 110 to 655 kbaud with a 20.97 MHz system
clock. Word length of either 8 or 9 bits is software selectable. Optional parity generation and detection
provide either even or odd parity check capability. Advanced error detection circuitry catches glitches
of up to 1/16 of a bit time in duration. Wake-up functions allow the CPU to run uninterrupted until mean-
ingful data is available.
