SVCall Priority
This field configures the priority level of SVCall. Configurable priority
values are in the range 0-7, with lower values having higher priority.
RO 0x000.0000 Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
