QTPNT
1
Queue transmit pointer. QTPNT is a 4-bit counter used to indicate the next data frame within the
transmit queue to be loaded into the SC1DR. This feature allows for ease of testability. This field
is writable in test mode only; otherwise it is read-only.
Receiver queue top-half full interrupt. When set, QTHFI enables an SCI1 interrupt whenever the
QTHF flag in QSCI1SR is set. The interrupt is blocked by negating QTHFI. This bit refers to the
queue locations SCRQ[0:7].
0 QTHF interrupt inhibited
1 Queue top-half full (QTHF) interrupt enabled
Receiver queue bottom-half full interrupt. When set, QBHFI enables an SCI1 interrupt whenever
the QBHF flag in QSCI1SR is set. The interrupt is blocked by negating QBHFI. This bit refers to
the queue locations SCRQ[8:15].
0 QBHF interrupt inhibited
1 Queue bottom-half full (QBHF) interrupt enabled
Transmitter queue top-half empty interrupt. When set, QTHEI enables an SCI1 interrupt
whenever the QTHE flag in QSCI1SR is set. The interrupt is blocked by negating QTHEI. This bit
refers to the queue locations SCTQ[0:7].
0 QTHE interrupt inhibited
1 Queue top-half empty (QTHE) interrupt enabled
Transmitter queue bottom-half empty interrupt. When set, QBHEI enables an SCI1 interrupt
whenever the QBHE flag in QSCI1SR is set. The interrupt is blocked by negating QBHEI. This
bit refers to the queue locations SCTQ[8:15].
0 QBHE interrupt inhibited
1 Queue bottom-half empty (QBHE) interrupt enabled
Reserved
Queue transmit enable. When set, the transmit queue is enabled and the TDRE bit should be
ignored by software. The TC bit is redefined to indicate when the entire queue is finished
transmitting. When clear, the SCI1 functions as described in the previous sections and the bits
related to the queue (Section 5.5 and its subsections) should be ignored by software with the
exception of QTE.
0 Transmit queue is disabled
1 Transmit queue is enabled
