ELCR1—Master Controller Edge/Level Triggered Register
(LPC I/F—D31:F0)
Offset Address: 4D0h
Default Value:
In edge mode, (bit[x] = 0), the interrupt is recognized by a low to high transition. In
level mode (bit[x] = 1), the interrupt is recognized by a high level. The cascade
channel, IRQ2, the heart beat timer (IRQ0), and the keyboard controller (IRQ1),
cannot be put into level mode.
