Errata: EP9307 - Silicon Revision: E2
Reference EP9307 Data Sheet revision DS667PP4 dated March 2005.
Determining the Silicon Revision of the Integrated Circuit
On the front of the integrated circuit, directly under the part number, is an alpha-numeric line. Characters 5
and 6 in this line represent the silicon revision of the chip. For example, this line indicates that the chip is a
“E2” revision chip:
EFWAE2AM0340
This Errata is applicable only to the E2 revision of the chip.
Please refer to AN273, “EP93xx Rev E Design Guidelines” (Cirrus Logic document AN273REV3) for
additional information.

Description
Disabling audio transmit by clearing the TEN bit in one of the AC97TXCRx registers will not clear out any
remaining bytes in the TX FIFO. If the number of bytes left in the FIFO is not equal to a whole sample or
samples, this will throw off subsequent audio playback causing distortion or channel swapping.
Workaround
To stop audio playback, do the following:
1) Pause DMA
2) Poll the AC97SRx register until either TXUE or TXFE is set.
3) Clear the TEN bit.
This ensures that the TX FIFO is empty before the transmit channel is disabled.
