ISCR is an 8-bit readable/writable register that selects level sensing or falling-edge sensing of the
inputs at pins
ISCR is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 and 6—Reserved: These bits can be written and read, but they do not select level or
falling-edge sensing.
Bits 5 to 0—IRQ
