C6713B Mcbsp Spi

Started by Dave October 10, 2005
Hi all,

Can anyone tell me if multiword frames work under SPI on this chip?
The data sheet spra551a says it should but a help note in the
knowledge base says:
##############################
C6000 McBSP in SPI Mode

Problem:
Can the C6000 McBSP in SPI Mode be used with multi-word frames?

Solution:
The C6000 McBSP in SPI Mode will work only with single-element single-
phase frames. A Frame Sync (a.k.a. Chip Select in SPI mode) signal is
required to be asserted and de-asserted for each element. Multi-word
frames cannot be used in SPI Mode. However, if four 8-b data needs to
be transacted on the SPI pins per Chip Select, the McbSP can be
programmed to do a single 32-b transfer. In this case, the FS/CS will
be asserted continuously for the 32-bits of data and then de-
asserted.

Help!!!!!

TIA,
Dave
