Description
INT IRQ: Indicates that an IRQ was asserted because an INT PTD was
completed, or the PTDs corresponding to the bits set in the INT IRQ
Mask AND or INT IRQ Mask OR register bits combination were
completed.
0 — No IRQ assertion determined by the completion of INT PTDs
1 — IRQ asserted because of completing INT PTD.
For details, see
signals are running stable. Useful after a power-on or wake-up cycle.
0 — No CLKREADY event has occurred
1 — INT generated because of a CLKREADY event.
Host Controller Suspend: Indicates that the Host Controller has
entered suspend mode.
0 — No INT generated because of the Host Controller entering suspend
mode
1 — INT generated because of the Host Controller entering suspend
mode.
If the ISR accesses the ISP1760, it will wake up for the time specified in
bits 31 to 16 of the Power Down Control register.
reserved; write logic 0
DMA EOT Interrupt: Indicates DMA transfer completion.
0 — DMA transfer is not complete
1 — IRQ asserted because the DMA transfer is complete.
reserved; write logic 0
0 — No SOF event has occurred
1 — An SOF event has occurred.
