Description
Soft Chip Reset.
A write of 1 causes a soft reset to the ADSP-2192. A write of
0 has no effect. Always reads 0. Soft Reset affects the DSPs
and the GPIOs. Soft Reset does not affect the PCI, USB,
Mailboxes, AC'97, or EEPROM.
Note that the DSP memory pipeline (last 2 writes per bank) is
lost upon reset. If desired, it may be flushed by three writes
in a row to the same location.
Note: This bit resets to zero.
