Description
Bit[2]
:
Encoder stop because the internal
reason:
0•>encoder normal operation (compare
&
connect complete, encoder local reset,
external reset).
1•>Encoder
stop
because
the
internal
reason,(FLAG6,,BOVF, MSOVF are set).
Bit[3]:Compare and connect operation symbol :
0•>not connect the coding (compare
&
connect complete, compare
stop, external reset),
&
connect
1•>execute the coding connect operation
(compare & connect command).
Note:
During the compare
&
connect, send the
encoder start command, it equal to send
compare & connect command directly.
So there can clear the compare
connect symbol.

Bit[5] :Input buffer overflow symbol:
0•> input buffer normal, (this register read
data, codec local reset, external reset)
1•>input
buffer
overflow,
(input
buffer
overflow).
Bit[6]: External DRAM write overflow symbol:
0•> external DRAM normal write,
(this
register read data, codec local reset,
external reset).
1•> external DRAM write overflow
Bit[7]: Shock symbol:
0•> normal operation, no shock, (this register
read data, ESP operate mode from
straight in switch to shockproof mode,
external reset).
1•> CD shock, (detect the CD vibrate)
