Note:
8.4.3
ICR1 is a 16-bit register that specifies the detection mode for external interrupt input pins IRQ0 to
IRQ5 individually: rising edge, falling edge, high level, or low level. This register is initialized to
H′4000 by a power-on reset or manual reset, but is not initialized in standby mode.

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Description
All Interrupt Mask
When this bit is set to 1, all interrupt requests
are masked while low level is input to the NMI
pin. In standby mode, an NMI interrupt is
masked.
0: When the NMI pin is low, all interrupt requests
1: When the NMI pin is low, all interrupt requests
Interrupt Request Level Detection
Enables or disables the use of pins IRQ3 to
IRQ0 as four independent interrupt pins. The
IRQ4 and IRQ5 pins are not affected.
0 : Use of pins IRQ3 to IRQ0 as four
1 : Use of pins IRL3 to IRL0 as encoded 15 level
