To cancel module standby mode and resume the supply of clock to the HAC, write 1 to the
MSTP0 bit in MSTPCR. After that, it enables all accesses to the HAC.
An example of the procedure to enter the module standby mode is shown below.
1. Check that all data transactions have ended. Also check that the transmit buffer of the HAC is
2. Disable all DMA requests and interrupt requests.
3. Place the codec into power-down mode.
4. Write 1 to the MSTP0 bit in MSTPCR.
25.5.6
The HAC_SYNC signal is generated by the HAC to indicate the position of slot 0 within a frame.
25.5.7
AC'97 Component Specification, Revision 2.1
empty and the receive buffer of the HAC has been read out to be empty.
