20.5.3.7.1 System Handler Priority Register 2
20.5.3.6 Configuration and Control Register
20.5.3.7 System Handler Priority Registers
The CCR is a read-only register and indicates some aspects of the behavior of the
Cortex-M0 processor. See the register summary in
The bit assignments are:
Table 251. CCR bit assignments
The SHPR2-SHPR3 registers set the priority level, 0 to 3, of the exception handlers that
have configurable priority.
SHPR2-SHPR3 are word accessible. See the register summary in
attributes.
To access to the system exception priority level using CMSIS, use the following CMSIS
functions:
The input parameter IRQn is the IRQ number, see
The system fault handlers, and the priority field and register for each handler are:
Table 252. System fault handler priority fields
Each PRI_N field is 8 bits wide, but the processor implements only bits[7:6] of each field,
and bits[5:0] read as zero and ignore writes.
The bit assignments are:

Function
Reserved.
Always reads as one, indicates 8-byte stack alignment on
exception entry.
On exception entry, the processor uses bit[9] of the stacked PSR
to indicate the stack alignment. On return from the exception it
uses this stacked bit to restore the correct stack alignment.
Reserved.
Always reads as one, indicates that all unaligned accesses
generate a HardFault.
