Section 7 Interrupt Controller (INTC)
7.3.4 Interrupt Control Register 2 (ICR2)
The ICR2 is a 16-bit read/write register that sets the detection mode to external interrupt input pins
PINT0 to PINT15. This register is initialized to H'0000 at power-on reset or manual reset, but is
not initialized in standby mode.
