Section 5 Interrupt Controller
Interrupt Priority Register B (IPRB)
IPRB is an 8-bit readable/writable register in which interrupt priority levels can be set.
IPRB is initialized to H'00 by a reset and in hardware standby mode.
Bit 7—Priority Level B7 (IPRB7): Selects the priority level of 8-bit timer channel 0, 1 interrupt
requests.
