Table 45:
Read this register to get the ID of the ISP1161 silicon chip. The high byte stands for
the product name (here 61H stands for ISP1161). The low 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)
