Queued Serial Multi-Channel Module
15-66
Read Status Register with TC = 1,
Write SCTQ[0:n] (Clears TC)
Read Status Register with QTHE=1
Write QTHE = 0 (and QBHE if
Transmitting More than 8 Data
Frames)
If Transmitting Greater
Than 8 Data Frames on Wrap
Read QBHE=1,Write QBHE=0
Write New Data to SCTQ[8:15]
No
Write QTSZ=n for First
Pass Use of the Queue
Enable Queue Interrupt
QTHEI = 1,
If Transmitting Greater
than 16 Data Frames,
Enable Queue Interrupt
QBHEI = 1
Set QTE and TE = 1
QTHE = 1?
QBHE = 1?
Reset
No
Yes

MPC561/MPC563 Reference Manual, Rev. 1.2
Figure 15-34. Queue Transmit Flow
Yes
If Finished Transmitting,
Then Clear QTE and/or TE
Read QTHE=1, Write QTHE=0
Write New Data SCTQ[0:7]
To Wrap, Write New QTSZ=n
Set QTWE (Previous QTSZ
Must Have Equaled 16)
Configure the Transmit Flow
for First Use of the Queue.
