SCP_CLK frequency1,2
1. The specification fspisck indicates the maximum speed of the hardware. The system designer should be aware that
the actual maximum speed of the communication port may be limited by the firmware application. Flow control using
the SCP_BSY pin should be implemented to prevent overflow of the input data buffer. At boot the maximum speed
is Fxtal/3.
2. When SCP1 is in SPI slave mode, very slow rise and fall times of the SCP_CLK edges may make the edges of the
SCP_CLK more susceptible to noise, resulting in non-smooth edges. Any glitch at the threshold levels of the SCP
port input signals could result in abnormal operation of the port.
In systems that have noise coupling onto SCP_CLK, slow rise and fall times may cause host communication
problems. Increasing rise time makes host communication more reliable.
