Write Operation:

0 = No effect.

1 = Changes SysTick exception state to pending.

Read Operation:

0 = SysTick exception is not pending.

1 = SysTick exception is pending.

[25]

PENDSTCLR

SysTick Exception Clear-Pending Bit

Write Operation:

0 = No effect.

1 = Removes the pending state from the SysTick exception.

This is a write only bit. When you want to clear

PENDST bit, you must “write 0 to

PENDSTSET and write 1 to PENDSTCLR” at the same time.

ISRPREEMPT

If Set, A Pending Exception Will Be Serviced On Exit From The Debug Halt State

This bit is read only.

[22]

ISRPENDING

Interrupt Pending Flag, Excluding NMI And Faults:

0 = Interrupt not pending.

1 = Interrupt pending.

This bit is read only.

[21:18]

Reserved

Reserved.

[17:12]

VECTPENDING

Indicates The Exception Number Of The Highest Priority Pending Enabled
Exception:

0 = No pending exceptions.

Non-zero = Exception number of the highest priority pending enabled exception.

[11:6]

Reserved

Reserved.

[5:0]

VECTACTIVE

Contains The Active Exception Number

0 = Thread mode.

Non-zero = Exception number of the currently active exception.
