The following applies to the registers used in the TZPC.
Place the TZPC in a secure area of memory to ensure TrustZone security.
The base address of the component is not fixed and can be different for any particular system implementation. However, the offset of any particular register from the base address is fixed.
You must not access reserved or unused address locations because this can result in unpredictable behavior of the device.
You must write reserved or unused register bits as zero and ignore them on read unless otherwise stated in the relevant text.
All register bits are reset to a logic 0 by a system or power-on reset unless otherwise stated in the relevant text.
All registers support read and write accesses unless otherwise stated in the relevant text. A write updates the contents of a register and a read returns the contents of the register.
You can access all registers with zero wait states.
