8.13 System Vector Tags

The System Vector Tags are tags that may be replaced by the user to take control over several decoder

functions.

8.13.1 AudioInt, 0x20

Normally contains the following VS DSP assembly code:

jmpi DAC_INT_ADDRESS,(i6)+1

The user may, at will, replace the ﬁrst instruction with a jmpi command to gain control over the audio

interrupt.

8.13.2 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.

8.13.3 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.

8.13.4 ModuInt, 0x23

Normally contains the following VS DSP assembly code:

jmpi MODU_INT_ADDRESS,(i6)+1

The user may, at will, replace the instruction with a jmpi command to gain control over the AD Modu-

lator interrupt.
