C6746 McBSP bit reversal problem

UNA
Mastermind 7980 points

Hello,

I tried McBSP receive 32-bit reversal on C6746 device.

but, I can not receive 32-bit element(LSB first). (Actual received data are all 0.)

As expected, the transmitting side is reversed.

My register settings are shown below(According to the document[23.2.5.5.7 32-Bit Bit Reversal: RWDREVRS, XWDREVRS](SPRUH80A) ):

　RCR = 0x00A80FB0

  XCR = 0x00A80FB0

  SPCR = 0x02230027

Howerver, RCR.RCOMPAND = 0 and RCR.RWDREVRS = 1, I can receive 32-bit reversed data.

The above settings is correct ?

regards,

Chii
