DREQ Polarity:
1 — Indicates that the DREQ output is active HIGH
0 — Indicates active LOW
reserved; write logic 0
Interrupt Polarity:
0 — Active LOW
1 — Active HIGH
Interrupt Level:
0 — INT is level triggered.
1 — INT is edge triggered. A pulse of certain width is generated.
Global Interrupt Enable: This bit must be set to logic 1 to enable the IRQ signal
assertion.
0 — IRQ assertion is disabled. IRQ will never be asserted, regardless of other settings or
IRQ events.
1 — IRQ assertion is enabled. IRQ will be asserted according to the Interrupt Enable
register, and events setting and occurrence.
