AT91SAM9G45
absence of AC97CK, AC97FX is treated as an asynchronous (regarding AC97FX) input used to
signal a warm reset to AC97 Codec.
This is the right way to perform a warm reset:
The application can check that operations have resumed by checking SOF flag in the
AC97C_SR register or wait for an interrupt notice if SOF is enabled in AC97C_IMR.
• Set WRST in the AC97C_MR register.
• Wait for at least 1us
• Clear WRST in the AC97C_MR register.
