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 IRQ5 to IRQ0.
The ISCR registers are initialized to H'0000 by a reset and in hardware standby mode.
Bits 15 to 12—Reserved: These bits are always read as 0, and should only be written with 0.
Bits 11 to 0—IRQ5 Sense Control A and B (IRQ5SCA, IRQ5SCB) to IRQ0 Sense Control A
and B (IRQ0SCA, IRQ0SCB)
