a. You can change the priority of this exception. See System Handler Priority Registers bit assignments on page 8-29. Settable
is an NVIC priority value of 0 to N, where N is the largest priority value implemented. Internally, the highest user-settable
priority (0) is treated as 4. You can enable or disable this fault. See System Handler Control and State Register bit assignments
on page 8-30.

Description
Reserved
System service call with SVC instruction. This is
synchronous.
Debug monitor, when not halting. This is synchronous, but
only active when enabled. It does not activate if lower
priority than the current activation.
Reserved
Pendable request for system service. This is asynchronous
and only pended by software.
System tick timer has fired. This is asynchronous.
Asserted from outside the core, INTISR[239:0], and fed
through the NVIC (prioritized). These are all asynchronous.
