Power Down Control register (address 0354h) bit description
Description
Clock Off Counter: Determines the wake-up status duration after any
wake-up event before the ISP1760 goes back into suspend mode. This
time-out is applicable only if, during the given interval, the host controller is
not programmed back to the normal functionality.
03E8h — The default value. It determines the default wake-up interval of
10 ms. A value of zero implies that the host controller never wakes up on
any of the events. This may be useful when using the ISP1760 as a
peripheral to save power by permanently programming the host controller
in suspend.
FFFFh — The maximum value. It determines a maximum wake-up time of
500 ms.
The setting of this register is based on the 100 kHz
frequency. It is a multiple of 10 s period.
Remark: In 16-bit mode, the default value is 17E8h. A write operation to
these bits with any value fixes the clock off counter at 1400h. This value is
equivalent to a fixed wake-up time of 50 ms.

1 — Internal regulators switch to low power mode (in suspend mode).
OC3_N Powered: Controls the powering of the overcurrent detection
circuitry for port 3.
0 — Overcurrent detection is powered on or enabled during suspend.

This may be useful when connecting a faulty device while the system is in
standby.
