u int16 DataBytes(void);
If the user has taken over the normal operation of the system by switching the pointer in UserCodec
to point to his own code, he may read data from the Data Interface through this and the following two
functions.
This function returns the number of data bytes that can be read.
10.15.4 GetDataByte(), 0x8
VS DSP C prototype:
u int16 GetDataByte(void);
Reads and returns one data byte from the Data Interface. This function will wait until there is enough
data in the input buffer.
10.15.5 GetDataWords(), 0xa
VS DSP C prototype:
void GetDataWords(register i0 y u int16 *d, register a0 u int16 n);
Read n data byte pairs and copy them in big-endian format (first byte to MSBs) to d. This function will
wait until there is enough data in the input buffer.
10.15.6 Reboot(), 0xc
VS DSP C prototype:
void Reboot(void);
Causes a software reboot, i.e. jump to the standard firmware without reinitializing the IRAM vectors.
This is NOT the same as the software reset function, which causes complete initialization.
