Available on a single SCI channel (SCI1) implemented by the queue transmit enable (QTE) bit set
by software. When enabled, (QTE = 1) the TDRE bit should be ignored by software and the TC bit
is redefined (as described later).
When the queue is disabled (QTE = 0), the SCI functions in single buffer transfer mode where the
queue size is set to one (QTSZ = 0000), and TDRE and TC function as previously defined.
Locations SCTQ[0:15] can be used as general purpose 9-bit registers. All other bits pertaining to
the queue should be ignored by software.
Programmable queue up to 16 transmits (SCTQ[0:15]) which may allow for infinite and
continuous transmits.
Available transmit wrap function to prevent message breaks for transmits greater than 16. This is
achieved by the transmit wrap enable (QTWE) bit. When QTWE is set, the hardware is allowed to
