CYRF69213
Clocking
The CYRF69213 internal oscillator outputs two frequencies, the Internal 24 MHz Oscillator and the 32 kHz Low power Oscillator.
The Internal 24 MHz Oscillator is designed such that it may be trimmed to an output frequency of 24 MHz over temperature and voltage
variation. With the presence of USB traffic, the Internal 24 MHz Oscillator can be set to precisely tune to USB timing requirements (24
MHz ± 1.5%). Without USB traffic, the Internal 24 MHz Oscillator accuracy is 24 MHz ± 5% (between 0°–70°C). No external compo-
nents are required to achieve this level of accuracy.
The internal low speed oscillator of nominally 32 KHz provides a slow clock source for the CYRF69213 in suspend mode, particularly
to generate a periodic wakeup interrupt and also to provide a clock to sequential logic during power up and power down events when
the main clock is stopped. In addition, this oscillator can also be used as a clocking source for the Interval Timer clock (ITMRCLK)
and Capture Timer clock (TCAPCLK). The 32 kHz Low power Oscillator can operate in low power mode or can provide a more accurate
clock in normal mode. The Internal 32 kHz Low power Oscillator accuracy ranges (between 0° – 70° C) as follows:
5V Normal mode: –8% to + 16%
5V LP mode: +12% to + 48%
When using the 32 kHz oscillator the PITMRL/H should be read until two consecutive readings match before sending/receiving data.
The following firmware example assumes the developer is interested in the lower byte of the PIT.
