VS1103B REGISTERS

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

Modulator interrupt.

8.13.5

TxInt, 0x24

Normally contains the following VS_DSP assembly code:

jmpi EMPTY_INT_ADDRESS,(i6)+1
