Description
Data Bus Width:
0 — Defines a 16-bit data bus width
1 — Sets a 32-bit data bus width
Remark: Setting this bit will affect all the controllers on the chip: host controller, peripheral
controller and OTG controller.
reserved; write logic 0
DACK Polarity:
1 — Indicates that the DACK input is active HIGH
0 — Indicates active LOW
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 IRQ signal assertion.
0 — IRQ assertion disabled. IRQ will never be asserted, regardless of other settings or
IRQ events.
1 — IRQ assertion enabled. IRQ will be asserted according to the HcInterruptEnable
register, and events setting and occurrence.
