10.4.3.11 Exception mask registers
The exception mask registers disable the handling of exceptions by the processor. Disable exceptions where they
might impact on timing critical tasks.
To access the exception mask registers use the MSR and MRS instructions, or the CPS instruction to change the
value of PRIMASK or FAULTMASK. See “MRS” on page 146, “MSR” on page 147, and “CPS” on page 143 for
more information.
