Description
IRL Pin Mode 1
Selects whether IRQ/IRL7 to IRQ/IRL4 are used as 4-
bit level-encoded interrupt requests or as four
independent interrupts.
0: IRQ/IRL7 to IRQ/IRL4 are used as the 4-bit level-
1: IRQ/IRL7 to IRQ/IRL4 are used as four independent
Note: The level-encoded IRL interrupt is not detected
IRQ/IRL Level-sense with holding function
Selects whether or not to use the holding function for
level-encoded IRL and level-sense IRQ interrupts.
0: IRQ level-sense and IRL interrupt requests are held
1: IRQ level-sense and IRL interrupt requests are not
Note: This setting is only valid for IRQ/IRL pins used as
Reserved
These bits are always read as 0. The write value
should always be 0.
