HPI Status Port [] [HPI: R]
Register Description
The HPI Status Port provides the external host processor with
the MailBox status bits plus several SIE status bits. This
register is not accessible from the on-chip CPU. The additional
SIE status bits are provided to aid external device driver
firmware development, and are not recommended for applica-
tions that do not have an intimate relationship with the on-chip
BIOS.
Reading from the HPI Status Port does not result in a CPU HPI
interface memory access cycle. The external host may contin-
uously poll this register without degrading the CPU or DMA
performance.
VBUS Flag (Bit 15)
The VBUS Flag bit is a read-only bit that indicates whether
OTG VBus is greater than 4.4V. After turning on VBUS,
firmware should wait at least 10 µs before this reading this bit.
1: OTG VBus is greater then 4.4V
0: OTG VBus is less then 4.4V
ID Flag (Bit 14)
The ID Flag bit is a read-only bit that indicates the state of the
OTG ID pin.
SOF/EOP2 Flag (Bit 12)
The SOF/EOP2 Flag bit is a read-only bit that indicates if a
SOF/EOP interrupt occurs on either Host/Device 2.
1: Interrupt triggered
0: Interrupt did not trigger
SOF/EOP1 Flag (Bit 10)
The SOF/EOP1 Flag bit is a read-only bit that indicates if a
SOF/EOP interrupt occurs on either Host/Device 1.
1: Interrupt triggered
0: Interrupt did not trigger
Reset2 Flag (Bit 9)
The Reset2 Flag bit is a read-only bit that indicates if a USB
Reset interrupt occurs on either Host/Device 2.
1: Interrupt triggered
0: Interrupt did not trigger

Mailbox In Flag (Bit 8)
The Mailbox In Flag bit is a read-only bit that indicates if a
message is ready in the incoming mailbox. This interrupt
clears when on-chip CPU reads from the HPI Mailbox register.
1: Interrupt triggered
0: Interrupt did not trigger
Resume2 Flag (Bit 7)
The Resume2 Flag bit is a read-only bit that indicates if a USB
resume interrupt occurs on either Host/Device 2.
1: Interrupt triggered
0: Interrupt did not trigger
Resume1 Flag (Bit 6)
The Resume1 Flag bit is a read-only bit that indicates if a USB
resume interrupt occurs on either Host/Device 1.
1: Interrupt triggered
0: Interrupt did not trigger
SIE2msg (Bit 5)
The SIE2msg Flag bit is a read-only bit that indicates if the
CY7C67200 CPU has written to the SIE2msg register. This bit
is cleared on an HPI read.
1: The SIE2msg register has been written by the CY7C67200
CPU
0: The SIE2msg register has not been written by the
CY7C67200 CPU
SIE1msg (Bit 4)
The SIE1msg Flag bit is a read-only bit that indicates if the
CY7C67200 CPU has written to the SIE1msg register. This bit
is cleared on an HPI read.
1: The SIE1msg register has been written by the CY7C67200
CPU
0: The SIE1msg register has not been written by the
CY7C67200 CPU
Done2 Flag (Bit 3)
In host mode the Done2 Flag bit is a read-only bit that indicates
if a host packet done interrupt occurs on Host 2. In device
