Register Description

The HPI Breakpoint register is a special on-chip memory location, which the external processor can access using normal HPI memory read/write cycles. This register is read-only by the CPU but is read/write by the HPI port. The contents of this register have the same effect as the Breakpoint register [0xC014]. This special Breakpoint register is used by software debuggers which interface through the HPI port instead of the serial port.

When the program counter matches the Breakpoint Address, the INT127 interrupt triggers. To clear this interrupt, a zero value must be written to this register.

Address (Bits [15:0])

The Address field is a 16-bit field containing the breakpoint address.

Register Description

The Interrupt Routing register allows the HPI port to take over some or all of the SIE interrupts that usually go to the on-chip CPU. This register is read-only by the CPU but is read/write by the HPI port. By setting the appropriate bit to ‘1’, the SIE interrupt is routed to the HPI port to become the HPI_INTR signal and also readable in the HPI Status register. The bits in this register select where the interrupts are routed. The individual interrupt enable is handled in the SIE interrupt enable register.

VBUS to HPI Enable (Bit 15)

The VBUS to HPI Enable bit routes the OTG VBUS interrupt to the HPI port instead of the on-chip CPU.

1:Route signal to HPI port

0:Do not route signal to HPI port

ID to HPI Enable (Bit 14)

The ID to HPI Enable bit routes the OTG ID interrupt to the HPI port instead of the on-chip CPU.

1:Route signal to HPI port

0:Do not route signal to HPI port

SOF/EOP2 to HPI Enable (Bit 13)

The SOF/EOP2 to HPI Enable bit routes the SOF/EOP2 interrupt to the HPI port.

1:Route signal to HPI port

0:Do not route signal to HPI port
