SReset1
DESCRIPTION
These 7 bits are reserved.
When set, synchronisation with PLUM on subcode transfer has failed; reset when
a logic 1 is written to this bit (Status2).
This bit is an active HIGH reset to the following blocks: Encoder/decoder, EFM
modulator, Encode control block, Serial input/output block and Encode subcode insert
block. The clock control, EFM PLL, tacho, motor interface and wobble interface remain
running.
Soft reset will reset the following registers: EFMPresetCount, EFMModulateConfig,
EFMModulateConfig2, EncodeXOffset, EncodeWriteControl, EncodeStartOffset,
EncodeStopOffset, SubPresetCount, SubConfig1, Subconfig2, SubStartData, SubData,
InputConfig, DecoMode, Output1, Output2 and Output3.
A soft reset is mandatory in the following cases:
1. After programming the BCLK clock
2. When switching from encode to decode
3. When switching from decode to encode.
