HPI Registers
There are five registers dedicated to HPI operation. In addition,
there is an HPI status port which can be addressed over HPI.
Each of these registers is covered in this section and are summa-
rized in
HPI Breakpoint Register [0x0140] [R]
Table 99. HPI Breakpoint Register
Register Description
The HPI Breakpoint register is a special on-chip memory location
that 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 that
interface through the HPI port instead of the serial port.
Interrupt Routing Register [0x0142] [R]
Table 100. Interrupt Routing Register
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

Table 98. HPI Registers
When the program counter matches the Breakpoint Address, the
INT127 interrupt triggers. To clear this interrupt, write a zero a to
this register.
Address (Bits [15:0])
The Address field is a 16-bit field containing the breakpoint
address.
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
