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.
