STV3550 external and internal memory mapping
Reset strategy
The internal and external memory maps in the STV3550 is described in
The chip includes three different types of reset:
1.
2.
3.
An external hard reset controlled by the NRESET pin and usually used for the power on
reset (POR).
An internal reset generated by the watchdog.
A soft reset controlled by the ST20 C2C200 CPU core.
