6.3.5
ISCRH and ISCRL select the source that generates an interrupt request from IRQ15 to IRQ0
input.
Upon changing the setting of ISCR, IRQnF (n = 0 to 15) in ISR is often set to 1 accidentally
through an internal operation. In this case, an interrupt exception handling is executed if an IRQn
interrupt request is enabled. In order to prevent such an accidental interrupt from occurring, the
setting of ISCR should be changed while the IRQn interrupt is disabled, and then the IRQnF in
ISR should be cleared to 0. However, the bits of this register cannot set the edge selections,
IRQnSR (n = 3 to 0) and IRQnSF (n = 3 to 0), for IRQ interrupt requests to exit from deep
software standby mode. For details, see section 24.2.8, Deep Standby Interrupt Edge Register
(DPSIEGR).
