Section 5 Interrupt Controller
ISCRH and ISCRL are 8-bit readable/writable registers that select rising edge, falling edge, or
both edge detection, or level sensing, for the input at pins IRQ7 to IRQ0.
Each of the ISCR registers is initialized to H'00 by a reset and in hardware standby mode.
ISCRH Bits 7 to 0, ISCRL Bits 7 to 0: IRQ7 Sense Control A and B (IRQ7SCA, IRQ7SCB) to
IRQ0 Sense Control A and B (IRQ0SCA, IRQ0SCB)

ISR is an 8-bit readable/writable register that indicates the status of IRQ7 to IRQ0 interrupt
requests.
ISR is initialized to H'00 by a reset and in hardware standby mode.
