66AK2G12: About ASRC data input/output

O.H

Part Number: 66AK2G12

Hi experts,

Please tell me about the ASRC built into the 66AK2G12.

Q1:Is it correct that the data input/output to ASRC must go through TeraNet_DMA? Or, is it possible to input data directly from McASP to ASRC, process it, and then output it again via ASRC in McASP?

Q2:For example, is it possible to take a signal at 96.1kHz from McASP, process it at 96kHz internally via ASRC, and then output it at 96.1kHz via ASRC again?

Q3:According to "11.1.3.3 ASRC Data Interface and Formats" in TRM, is it correct to truncate the MSB of a 32-bit input from McASP for a maximum 24-bit input/output? Or is it LSB truncation?

Best regards,
O.H
