CPU clock frequency used (default 96 MHz).
|
|
Please note that peripherals such as I2C or SPI might not work at
|
|
the specified clock frequency if the selected CPU clock frequency
|
|
is too low. These peripherals are clocked by the APB clock, which
|
|
has a clock rate of 32 MHz for CPU clock frequencies greater than
|
|
or equal to 32 MHz, but is equal to the CPU clock frequency for
|
|
CPU clock frequencies less than 32 MHz. Thus, for SPI, the APB
|
|
clock rate must be at least five times the SPI clock rate. For the
|
|
I2C hardware implementation, the APB clock rate must be at least
|
|
3 MHZ to use I2C in fast mode with a I2C clock rate of 400 kHz.
|
|
For the I2C software implementation, the maximum I2C clock rate
|
|
is 1/130 times the CPU clock rate.
