System Handler Priority Registers
The SHPR1-SHPR3 registers set the priority level, 0 to 15 of the exception handlers that have
configurable priority.
SHPR1-SHPR3 are byte accessible. See the register summary in
their attributes.
The system fault handlers and the priority field and register for each handler are:
Table 12-32. System fault handler priority fields
Each PRI_N field is 8 bits wide, but the processor implements only bits[7:4] of each field, and
bits[3:0] read as zero and ignore writes.
