Is SVC pendable on cortex-m?

loquat3

Hey.

I read ARMv7-M Arch manual.

SHCSR register have SVCALLPENDED bit.

So that, It seem SVC is pendable.

But, 'Priority escalation' is written,

When the group priority of a pending synchronous fault or supervisor call is lower than or equal to the
currently executing priority, inhibiting normal preemption. This applies to all synchronous exceptions, both
faults and SVCalls.

This seem SVC is not pendable.

Is SVC pendable? If true, how behaver?
