Conversion Frequency Divider

The conversion frequency divider allows for the conversion clock to be divided down from the base rate of 16 MHz. The conversion clock period must be long enough to ensure complete charge transfer phases. This can be verified on an oscilloscope by probing the electrode pins if a sensor is experiencing noise.

Divider | Base Frequency
--- | ---
/1 | 16 MHz
/2 | 8 MHz
/4 | 4 MHz
/8 | 2 MHz
/16 | 1 MHz
/32 | 500 kHz
/64 | 250 kHz
/128 | 125 kHz

Implementation Notes
The conversion clock divider works in series with the conversion charge and transfer phase lengths. The effective overall conversion rate is a function of the clock divider, the charge/hold phase length, and the transfer/sample phase length.

Affected Software Parameters
The Frequency_Divider parameter corresponds to the ui8FreqDiv member of the tSensor type in the CapTIvate Touch Library.
