INIT_RAM
RAM initialization
Address : 0xFF
Type: RO
Software Reset: 1
Hardware Reset: 0
Description:
The register is used to signal when the STA310 has finished to boot.
After a soft reset or a hardware reset, or a hardware reset, the host processor must wait until INIT_RAM hold
the value “1”.
the host can then start to configure the STA310 according to its application
APPENDIX A OVERVIEW OF THE CHIP
This STA310 is based on a very high performances low power general purpose DSP core, MMDSP+, and a set
of dedicated peripherals. Internal audio and system PLL allows to configure the chip for a wide range of audio
frequencies and DSP processing power (1 to 100 Mips).
