Data Sheet
The detailed register description is shown below.
USBCLC
Table 74
The state of the USB interface kernel clock is controlled by the register bit USBDISR.
The actual USB kernel clock state will be shown by the state bit USBDIS.
The register USBCLC is clocked with the bus clock to be able to switch the USB interface
controller clock on again, if it was off. If required, switching off the clock can be prevented
by the USB controller.
For on chip debugging support (OCDS) an additional bit USBGPSEN is introduced to
stop the peripheral clock for arbitrary lengths of time during debugging if this function is
enabled. If debugging mode is active, the peripheral core rejects write access to
registers connected to the peripheral clock.
To be compatible with previous C16x products an USBEX_DISR signal is provided to
disable the peripheral clock.
