So let's just ignore the clearance of these bits in isr().
+++++ SAI Transmit Control Register (I2S1_TCSR) : 32 : R/W : 0000_0000h
I'm talking about FWF and FRF bits, not TCSR as a register.
I have checked in the Vybrid and LS1 SoC datasheets, and they are all the Same as above, and nothing else.
Have I missed ?
What i.MX IC team told me is SAI ignores what we do to FWF and FRF, so you don't need to worry about it at all unless Vybrid makes them writable, in which case we may also need to clear these bits and confirm with Vybrid IC team if they're also W1C.
Well, if so, that's fine.
Thanks,
