1: Enable SOF/EOP timer interrupt
0: Disable SOF/EOP timer interrupt
Port A Wake Interrupt Enable (Bit 6)
The Port A Wake Interrupt Enable bit enables or disables the
remote wakeup interrupt for Port A.
1: Enable remote wakeup interrupt for Port A
0: Disable remote wakeup interrupt for Port A
Port A Connect Change Interrupt Enable (Bit 4)
The Port A Connect Change Interrupt Enable bit enables or
disables the Connect Change interrupt on Port A. This interrupt
triggers when either a device is inserted (SE0 state to J state) or
a device is removed (J state to SE0 state).
1: Enable Connect Change interrupt
0: Disable Connect Change interrupt
Done Interrupt Enable (Bit 0)
The Done Interrupt Enable bit enables or disables the USB
Transfer Done interrupt. The USB Transfer Done triggers when
either the host responds with an ACK, or a device responds with
any of the following: ACK, NAK, STALL, or Timeout. This
interrupt is used for both Port A and Port B.
1: Enable USB Transfer Done interrupt
0: Disable USB Transfer Done interrupt
Reserved
All reserved bits must be written as ‘0’.
Host n Status Register [R/W]
■ Host 1 Status Register 0xC090
■ Host 2 Status Register 0xC0B0
Figure 26. Host n Status Register
Register Description
The Host n Status register provides status information for host
operation. Pending interrupts can be cleared by writing a ‘1’ to
the corresponding bit. This register can be accessed by the HPI
interface.
VBUS Interrupt Flag (Bit 15)
The VBUS Interrupt Flag bit indicates the status of the OTG
VBUS interrupt (only for Port 1A). When enabled this interrupt
triggers on both the rising and falling edge of VBUS at 4.4 V. This
bit is only available for Host 1 and is a reserved bit in Host 2.
1: Interrupt triggered
0: Interrupt did not trigger
ID Interrupt Flag (Bit 14)
The ID Interrupt Flag bit indicates the status of the OTG ID
interrupt (only for Port 1A). When enabled this interrupt triggers
on both the rising and falling edge of the OTG ID pin. This bit is
only available for Host 1 and is a reserved bit in Host 2.
1: Interrupt triggered
0: Interrupt did not trigger
SOF/EOP Interrupt Flag (Bit 9)
The SOF/EOP Interrupt Flag bit indicates the status of the
SOF/EOP Timer interrupt. This bit triggers ‘1’ when the
SOF/EOP timer expires.
1: Interrupt triggered
0: Interrupt did not trigger
