This register is used to configure the internal regulator and the oscillator tuning capability.
This register is only used by the CY8CTMG20x, CY8CTST200 PSoC devices. In the table above, note that reserved bits are
grayed table cells and are not described in the bit description section below. Reserved bits must always be written with a
value of ‘0’. For additional information, refer to the

Description
Monitors activity on USB bus. This bit is only set by the hardware. Writing a ‘0’ clears this bit. Writing
a ‘1’ preserves its present state.
0
1
Controls the automatic tuning of the internal oscillator. Hardware locks the internal oscillator based on
the frequency of incoming USB data when this bit is set. Normally, this is set when the device is used
in a USB application.
0
