Revision 1.3
There are four categories of parameters, the
1
st
category can only be changed at initialization, the 2
nd
category
can be changed at run time only with precaution, the 3
rd
category has to be preset according to the
application and physical placement of micropone and speaker, the
4
th
category is read only status. When the
system is powered up or reset, the SW will initialize the proper register according to the strap options, then
wait in a loop for further instruction if it’s in external host mode (i.e., EEPROM, Serial Host Interface).
Once SW get the “GO” instruction (i.e., 0x1E3A = 0x0000), the initialization is considered done. The
system will be in “run” mode.
Parameters can only be changed at initialization stage

2. Mic_revert_mode
