Interrupt generation when the top half (SCTQ[0:7]) of the queue has been emptied (QTHE) and the
bottom half (SCTQ[8:15]) of the queue has been emptied (QBHE). This may allow for
uninterrupted and continuous transmits by indicating to the CPU that it can begin refilling the
queue portion that is now emptied.
— The QTHE bit is set by hardware when the top half is empty or the transmission has completed.
— The QBHE bit is set by hardware when the bottom half is empty or the transmission has

Programmable 4-bit register queue transmit size (QTSZ) for configuring the queue to any size up
to 16 transfers at a time. This value may be rewritten after transmission has started to allow for the
wrap feature.
4-bit status register to indicate the number of data transfers pending (QPEND). This register counts
down to all 0’s where the next count rolls over to all 1’s. This counter is writable in test mode;
otherwise it is read-only.
4-bit counter (QTPNT) is used as a pointer to indicate the next data frame within the transmit queue
to be loaded into the SC1DR. This counter is writable in test mode; otherwise it is read-only.
A transmit complete (TC) bit re-defined when the queue is enabled (QTE = 1) to indicate when the
entire queue (including when wrapped) is finished transmitting. This is indicated when QPEND =
1111 and the shifter has completed shifting data out. TC is cleared when the SCxSR is read with
TC = 1 followed by a write to SCTQ[0:15]. If the queue is disabled (QTE = 0), the TC bit operates
as originally designed.
When the transmit queue is enabled (QTE = 1), writes to the transmit data register (SC1DR) have
no effect.
