The "McASP system clock" in DM642
Could anybody tell what the frequency of "McASP system clock" in DM642. I used to think that was the same as the "AUXCLK". But recently, I found a sentence written in the "TMS320C6000 DSP Multichannel Audio Serial Port (McASP) Reference Guide"(spru041g.pdf),which said "Refer to device data manual for the McASP system clock source. This is not the same as AUXCLK". While in the DM642 datasheet, I could not find any information mentioning the "McASP system clock".
Any information is apprectiated, thank you!
