Read this register to get the ID of the ISP1160 silicon chip. The higher byte stands for
the product name. The lower byte indicates the revision number of the product
including engineering samples.

Description
reserved
0 — power-up value
1 — enables ClkReady interrupt
0 — power-up value
1 — enables HC suspended interrupt. When the microprocessor
wants to suspend the HC, the microprocessor must write to the
HcControl register. And when all downstream devices are
suspended, then the HC stops sending SOF; the HC is suspended
by having the HcControl register written into.
0 — power-up value
1 — enables the 32-bit operational register’s interrupt (if the HC
requires the operational register to be updated)
reserved
0 — power-up value
1 — enables the EOT interrupt which indicates an end of a
read/write transfer
0 — power-up value
1 — enables ATL interrupt. The time for this interrupt depends on
the number of clock bits set for USB activities in each ms.
0 — power-up value
1 — enables the interrupt bit due to SOF (for the microprocessor
DMA to get ISO data from the HC by first accessing the
HcDMAConfiguration register)
