10.5 HC miscellaneous registers
10.5.1
HcChipID register (27H—Read only)
Read this register to get the ID of the ISP1160 silicon chip. The high byte stands for
the product name (here 61H stands for the ISP1160). The low byte indicates the
revision number of the product including engineering samples.

6
ClkReady
0 — power-up value
1 — enables Clkready interrupt
5HC
Suspended
Enable
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.
4
OPR
Interrupt
Enable
0 — power-up value
1 — enables the 32-bit operational register’s interrupt (if the HC
requires the operational register to be updated)

reserved
2EOT
Interrupt
Enable
0 — power-up value
1 — enables the EOT interrupt which indicates an end of a
Read/Write transfer
1ATL
Interrupt
Enable
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
SOF
Interrupt
Enable
0 — power-up value
1 — enables the interrupt bit due to SOF (for the microprocessor
DMA to get ISO data from the HC by rst accessing the
HcDMAConguration register)
