Section 9 Interrupt Controller (INTC)
9.3.2
ICR1 is a 32-bit readable/writable register that specifies the individual input signal detection
modes of external interrupt input pins IRQ7/IRL7 to IRQ4/IRL4. This setting is valid only when
using IRL7 to IRL4 and IRL3 to IRL0 as IRQ independent interrupts input to set the IRLM0 and
IRLM1 bits to 1 in ICR0.

Description
IRL Pin Mode 1
Selects whether IRQ7/IRL7 to IRQ4/IRL4 are used as
the 4-bit encoded interrupt requests or as four
independent interrupts.
0: IRQ7/IRL7 to IRQ4/IRL4 are used as the 4-bit level-
1: IRQ7/IRL7 to IRQ4/IRL4 are used as four
Note: The level-encoded IRL interrupt is not detected
Reserved
These bits are always read as 0. The write value should
always be 0.
