Preliminary Specifications REV. E
Specifications in this manual are tentative and subject to change
Attach/Detach Function
5.1.2.5 PLL Lock Bit
The PLL lock bit is used to indicate when the PLL is first locked. Accordingly, after the PLL is enabled
and it has been given 2.0 ms to stabilize, the lock bit status should be checked. Once the lock bit is
HIGH, the USB check should be enabled. After this stage, the lock bit is no longer valid and should
not be monitored, unless the PLL is re-enabled.
5.2 Attach/Detach Function
The Attach/Detach Function can be used to attach or detach a USB function from the host without dis-
connecting the cable. When attaching a USB function, the connect registers should be set to 3 Hex at
the same time on or before the DC-DC Converter is enabled. Similarly, when detaching the connect
register, it should be set to 1 Hex when powering down the DC-DC Converter.
If you do not set the connect (address 1fh) to HIGH, the system will default to its normal mode.
Note: If the D+ is connected to ExtCAP, this mode will not work.
D+ is connected to ExtCAP through a 1.5 K resistor in compliance with the USB specification. USB
Suspend/Resume Function
