IRQ Polarity (IRQ_POL)
When cleared, this bit enables the IRQ line to function as an active low
output. When set, the IRQ output is active high. When the IRQ is configured
as an open-drain output (via the IRQ_TYPE bit), this bit is ignored, and the
interrupt is always active low.
0: IRQ active low output
1: IRQ active high output
RESERVED
IRQ Buffer Type (IRQ_TYPE)
When this bit is cleared, the IRQ pin functions as an open-drain output for
use in a wired-or interrupt configuration. When set, the IRQ is a push-pull
driver.
Note:
0: IRQ pin open-drain output
1: IRQ pin push-pull driver
