CLOCK_SPEED
Numerical Value of Clock Speed in Binary
The unit of measure is programmed in CLOCK_UNIT. The valid range is from 1 to 1023 when clock unit is
MHz and 4 to 1023 when clock unit is KHz. Examples with CLOCK_UNIT = 1:
• For 48 MHz: 0b00_0011_0000 (48) (Default)
• For 24 MHz: 0b00_0001_1000 (24)

CLOCK_UNIT
Examples with CLOCK_UNIT = 0:
• For 100 kHz: 0b00_0110_0100 (100)
• For 500 kHz: 0b01_1111_0100 (500)
This read-only field is reserved and always has the value zero.
Unit of measurement encoding for Clock Speed
Specifies the unit of measure for the clock speed.
0b0 kHz Speed (between 1 kHz and 1023 kHz)
0b1 MHz Speed (between 1 MHz and 1023 MHz)
46.4.3 Status Register (USBDCD_STATUS)
The status register provides the current state of the module for system software
monitoring.
Address: USBDCD_STATUS is 4003_5000h base + 8h offset = 4003_5008h
