Good time.
I still cant figure out, how to use this MBuf mode.
So i sending data byte by byte "manually". For example:
scilinREG->TD = 0xAA;
scilinREG->TD = 0xBB;
scilinREG->TD = 0xCC;
and i can see it on oscillograph.
But when I'm enabling MBUFF mode (scilinREG->GSR1 |= 1<<10) oscillograph siply shows nothing 0.
But I found this in spnu449:
26.5.2.2 Transmitting Data in Multi-Buffer Mode
Multi-buffer mode is selected when the MBUF MODE bit in SCIGCR1 is set to 1. Like single-buffer mode,
you can use the polling, interrupt, or DMA method to write the data to be transmitted. The transmitted data
has to be written to the SCITD registers. SCI waits for data to be written to the SCITD register and
transfers the programmed number of bytes to SCITXSHF to transmit one by one automatically.
How I should use this SCITXSHF register? And where I should write the number of bytes has to be transmitted?
Thank you in advance.
