NOTE
If TBC_CLK_PS is not set to disabled, it must not be changed to any other
value besides disabled. If TBC_CLK_PS is set to disabled it can be changed
to any other value.

ADC Time Base Counter Registers (ADC_TBCR)
The ADC_TBCR contains the current value of the time base counter. ADC_TBCR can be accessed by
configuration commands sent to ADC0 or to ADC1. A data write to ADC_TBCR using a configuration
command sent to ADC0 writes the same memory location as a write using a configuration command sent
to ADC1.

TBC_
CLK_PS
[0:3]
Time base counter clock prescaler. Contains the system clock divide factor for the time base counter. It controls the
accuracy of the time stamp. The prescaler is disabled when TBC_CLK_PS is set to 0b0000.
