The GRTC peripheral supports split security, where the split security features can have different security attributes than the GRTC peripheral.
Split security settings are configured in SPU.
The following GRTC features have split security attributes:
- Each compare/capture channel at CC[n] register group - The same security attribute applies to the corresponding channels for,
- Each INTENm/INTENSETm/INTENCLRm/INTENPENDm - The same security attribute applies to the following registers
- Registers, tasks, and events associated with the PWM function have configurable security attribute.
- Registers, tasks, and events associated with the CLKOUT and CLKCFG functions have configurable security attribute.
INTERVAL has same security attribute as the CC[0] register group.
For more information on GRTC split ownership and security attributes, see Split Security.
Interrupts
GRTC provides multiple interrupts. Each interrupt is associated with its own set of INTENm/INTENSETm/INTENCLRm/INTENPENDm register. All events are routed to each of INTENm/INTENSETm/INTENCLRm/INTENPENDm registers, however only those events matching the security attributes can be accessible using the INTENm/INTENSETm/INTENCLRm/INTENPENDm registers.
