11.9.1.8
The SCB_SHPR1-SCB_SHPR3 registers set the priority level, 0 to 15 of the exception handlers that have configurable pri-
ority. They are byte-accessible.
The system fault handlers and the priority field and register for each handler are:
Table 11-32. 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.
