SERIRQ Output Select
These bits select the state of the output on the pin for
LPC host interrupt requests (HIRQ15, HIRQ14,
HIRQ13, HIRQ8, HIRQ7, HIRQ5, HIRQ4, and
HIRQ3).
0: [When host interrupt request is cleared]
SERIRQ pin output is in the Hi-Z state.
[When host interrupt request is set]
SERIRQ pin output is low.
1: [When host interrupt request is cleared]
SERIRQ pin output is low.
[When host interrupt request is set]
SERIRQ pin output is in the Hi-Z state.
