The ISCR registers are 16-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.
The ISCR registers are initialized to H'0000 by a reset and in hardware standby mode.
They are not initialized in software standby mode.
Bits 15 to 0: IRQ7 Sense Control A and B (IRQ7SCA, IRQ7SCB) to IRQ0 Sense Control A and
B (IRQ0SCA, IRQ0SCB)
