hi team,
my customer want to use DM6437 Mcbsp as slave, but found in Mcbsp user guide :
The McBSP requires an active edge of the slave-enable (SS) signal on the FSX input for each transfer.
This means that the master device must assert the slave-enable signal at the beginning of each transfer,
and deassert the signal after the completion of each packet transfer; the slave-enable signal cannot
remain active between transfers.
in my understanding, that means if use Mcbsp as SPI mode, when transfer one byte, it should require one low pluse in SS.
is it right? customer want to use EDMA to transfer data in host side, that mean host just hold low in SS when the data was transfered.
so the host can not met DM6437 Mcbsp requirement. is there any method to walk around the issue? your comments is appreciate. thanks in advanced.
