1.
Determining preemption of an exception uses only the group priority field.
• SYSRESETREQ: System Reset Request
0: No system reset request.
1: Asserts a signal to the outer system that requests a reset.
This is intended to force a large system reset of all major components except for debug. This bit reads as 0.
• VECTCLRACTIVE
Reserved for Debug use. This bit reads as 0. When writing to the register, write 0 to this bit, otherwise the behavior is
unpredictable.
• VECTRESET
Reserved for Debug use. This bit reads as 0. When writing to the register, write 0 to this bit, otherwise the behavior is
unpredictable.
