5.2.4
ISCR (composed of ISCRH and ISCRL) is a 16-bit readable/writable register that selects rising
edge, falling edge, or both edge detection, or level sensing, for the input at pins IRQ7 to IRQ0.
ISCR is initialized to H'0000 by a reset and in hardware standby mode.
Bits 15 to 0—IRQ7 Sense Control A and B (IRQ7SCA, IRQ7SCB) to IRQ0 Sense Control A
