timeout 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
±
40 % LazyClock
frequency. It is a multiple of 10
μ
s period. In 16-bit mode, a write
operation to these bits with any value will determine a fixed wake-up
time of 50 ms.
