 *

 *   QSM -- Queued Serial Module

 *

 * The QSM contains two serial interfaces: (a) the queued serial

 * peripheral interface (QSPI) and the serial communication interface

 * (SCI). The QSPI provides peripheral expansion and/or interprocessor

 * communication through a full-duplex, synchronous, three-wire bus. A

 * self contained RAM queue permits serial data transfers without CPU

 * intervention and automatic continuous sampling. The SCI provides a

 * standard non-return to zero mark/space format with wakeup functions

 * to allow the CPU to run uninterrupted until woken

 *

 * For more information, refer to Motorola's "Modular Microcontroller

 * Family Queued Serial Module Reference Manual" (Motorola document

 * QSMRM/AD).
