See Register blocks for definitions of the standard register block header fields.

Channel count

The channel count field contains the number of clocks, excluding the core and reference clocks.

RBB+0x0C	Channel count				RO -

Reference clock period

The reference clock period field contains the nominal period of the reference clock in nanoseconds as a fractional value, consisting of a 16-bit numerator and a 16-bit denominator.

Core clock period

The core clock period field contains the nominal period of the core clock in nanoseconds as a fractional value, consisting of a 16-bit numerator and a 16-bit denominator.

Core clock frequency

The core clock frequency field contains the measured core clock frequency in Hz, measured relative to the reference clock.

RBB+0x1C	Core clock frequency (Hz)				RO -

Channel clock frequency

The channel clock frequency fields contain the measured channel clock frequency in Hz, measured relative to the reference clock. There is one register per channel.
