SOF/EOP2 to CPU Enable
(Bit 12)
The SOF/EOP2 to CPU Enable bit routes the SOF/EOP2
interrupt to the on-chip CPU. Since the SOF/EOP2 interrupt
can be routed to both the on-chip CPU and the HPI port the
firmware must ensure only one of the two (CPU, HPI) resets
the interrupt.
1:
Route signal to CPU
0:
Do not route signal to CPU
SOF/EOP1 to HPI Enable
(Bit 11)
The SOF/EOP1 to HPI Enable bit routes the SOF/EOP1
interrupt to the HPI port.
1:
Route signal to HPI port
0:
Do not route signal to HPI port
SOF/EOP1 to CPU Enable
(Bit 10)
The SOF/EOP1 to CPU Enable bit routes the SOF/EOP1
interrupt to the on-chip CPU. Since the SOF/EOP1 interrupt
can be routed to both the on-chip CPU and the HPI port the
firmware must ensure only one of the two (CPU, HPI) resets
the interrupt.
1:
Route signal to CPU
0:
Do not route signal to CPU
Reset2 to HPI Enable
(Bit 9)
The Reset2 to HPI Enable bit routes the USB Reset interrupt
that occurs on Device 2 to the HPI port instead of the on-chip
CPU.
1:
Route signal to HPI port
0:
Do not route signal to HPI port
HPI Swap 1 Enable
(Bit 8)
Both HPI Swap bits (bits 8 and 0) must be set to identical
values. When set to ‘00’, the most significant data byte goes
to HPI_D[15:8] and the least significant byte goes to
HPI_D[7:0]. This is the default setting. By setting to ‘11’, the
most significant data byte goes to HPI_D[7:0] and the least
significant byte goes to HPI_D[15:8].
Resume2 to HPI Enable
(Bit 7)
The Resume2 to HPI Enable bit routes the USB Resume
interrupt that occurs on Host 2 to the HPI port instead of the
on-chip CPU.
1:
Route signal to HPI port
0:
Do not route signal to HPI port
Resume1 to HPI Enable
(Bit 6)
The Resume1 to HPI Enable bit routes the USB Resume
interrupt that occurs on Host 1 to the HPI port instead of the
on-chip CPU.
1:
Route signal to HPI port
0:
Do not route signal to HPI port
Done2 to HPI Enable
(Bit 3)
The Done2 to HPI Enable bit routes the Done interrupt for
Host/Device 2 to the HPI port instead of the on-chip CPU.
1:
Route signal to HPI port
0:
Do not route signal to HPI port
Done1 to HPI Enable
(Bit 2)
The Done1 to HPI Enable bit routes the Done interrupt for
Host/Device 1 to the HPI port instead of the on-chip CPU.
1:
Route signal to HPI port
0:
Do not route signal to HPI port
Reset1 to HPI Enable
(Bit 1)
The Reset1 to HPI Enable bit routes the USB Reset interrupt
that occurs on Device 1 to the HPI port instead of the on-chip
CPU.
1:
Route signal to HPI port
0:
Do not route signal to HPI port
HPI Swap 0 Enable
(Bit 0)
Both HPI Swap bits (bits 8 and 0) must be set to identical
values. When set to ‘00’, the most significant data byte goes
to HPI_D[15:8] and the least significant byte goes to
HPI_D[7:0]. This is the default setting. By setting to ‘11’, the
most significant data byte goes to HPI_D[7:0] and the least
significant byte goes to HPI_D[15:8].
