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
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
