usb31ctr

         Contains settings that control usb31_clk generated from PLL.


Module Instance	Base Address	Register Address
`i_clk_mgr__clkmgr_csr__10d10000__ctlgrp__SEG_L4_SHR_ClockManager_0x0_0x1000`	`0x10D100D0`	`0x10D100F8`

Size: 32

Offset: 0x28

Access: RW

Access mode: PRIVILEGEMODE

Note: The processor must make a privileged bus access to this register. You can configure processor mode settings in the control registers of the ARM Cortex-A53 MPcore processor. For more information about processor modes, please refer to the ARM Infocenter.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
