Description
Level-sense IRQ/IRL with holding function
Selects whether or not to use the holding function for
level-sense IRQ and IRL interrupts.
0: Level-sense IRQ and IRL interrupt requests are held
1: Level-sense IRQ and IRL interrupt requests are not
Rewriting to this bit should be performed by the
initialization routine before canceling the masking
(INTMASK0 and INTMASK1) for the IRQ interrupts and
IRL interrupt. After this, do not rewrite this bit until
power-on reset or manual reset is made. The initial
value is 0, however. it is recommended to use INTC
after this bit has been set to 1 by the initialization
routine.
For the details of the operation when this bit is set to 0,
refer to section 10.4.2, IRQ Interrupts, section 10.4.3,
IRL Interrupts, section 10.7.1, Example of Handing
Routine of IRL Interrupts and Level Detection IRQ
Interrupts when ICR0.LVLMODE = 0, and section
10.7.3, Clearing IRQ and IRL Interrupt Requests.
Reserved
These bits are always read as 0. The write value
should always be 0.
