Address (Bits [6:0])

The Address field contains the value of the USB address for the next device that the host is going to communicate with. This value must be written by firmware.

Reserved

Write all reserved bits with ’0’.

Register Description

The Host n Interrupt Enable register enables control over host related interrupts.

In this register a bit set to ‘1’ enables the corresponding interrupt while ‘0’ disables the interrupt.

VBUS Interrupt Enable (Bit 15)

The VBUS Interrupt Enable bit enables or disables the OTG VBUS interrupt. When enabled this interrupt triggers on both the rising and falling edge of VBUS at the 4.4V status (only supported in Port 1A). This bit is only available for Host 1 and is a reserved bit in Host 2.

1:Enable VBUS interrupt

0:Disable VBUS interrupt

ID Interrupt Enable (Bit 14)

The ID Interrupt Enable bit enables or disables the OTG ID interrupt. When enabled this interrupt triggers on both the rising and falling edge of the OTG ID pin (only supported in Port 1A). This bit is only available for Host 1 and is a reserved bit in Host 2.

1:Enable ID interrupt

0:Disable ID interrupt
