42.4.6.1 Frequency monitor register
Table 930. Register overview: CGU (base address 0x4005 0000)
The CGU can report the relative frequency of any operating clock. The clock to be
measured must be selected by software, while the fixed-frequency IRC clock fref is used
as the reference frequency. A 14-bit counter then counts the number of cycles of the
measured clock that occur during a user-defined number of reference-clock cycles. When
the MEAS bit is set, the measured-clock counter is reset to 0 and counts up, while the
9-bit reference-clock counter is loaded with the value in RCNT and then counts down
