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 onchip 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].
