Description:
I2C speed setting between ~39kHz and 400kHz.
The value of this parameter must be computed with the following formula
based on the wanted speed:
=

CSpeed
Note:
Speeds greater than 100kHz have some limitations (see page 17).
Do not use a speed greater than 400kHz (<24). Greater speed will not
work.
Default value:
99 (100kHz)
Examples:
Most common speeds:
100kHz : I2CSPD = 99
400kHz : I2CSPD = 24
