10. VS1011E REGISTERS
10.9 System Vector Tags
The System Vector Tags are tags that may be replaced by the user to take control over several decoder
functions.
10.9.1 AudioInt, 0x20
Normally contains the following VS DSP assembly code:
jmpi DAC_INT_ADDRESS,(i6)+1
The user may, at will, replace the instruction with a jmpi command to gain control over the audio
interrupt.
10.9.2 SciInt, 0x21
Normally contains the following VS DSP assembly code:
jmpi SCI_INT_ADDRESS,(i6)+1
The user may, at will, replace the instruction with a jmpi command to gain control over the SCI interrupt.
10.9.3 DataInt, 0x22
Normally contains the following VS DSP assembly code:
jmpi SDI_INT_ADDRESS,(i6)+1
The user may, at will, replace the instruction with a jmpi command to gain control over the SDI interrupt.
10.9.4 UserCodec, 0x0
Normally contains the following VS DSP assembly code:
jr
nop
If the user wants to take control away from the standard decoder, the first instruction should be replaced
with an appropriate j command to user’s own code.
