Each PRI_N field is 8 bits wide, but the EFM32 implements only bits[7:5] of each field, and bits[4:0] read
as zero and ignore writes.
The bit assignments are:
Table 4.22. SHPR1 register bit assignments
The bit assignments are:
Table 4.23. SHPR2 register bit assignments
The bit assignments are:
Table 4.24. SHPR3 register bit assignments
The SHCSR enables the system handlers, and indicates:
