clock to SYSCLK ratio. Note that frequencies between 400 MHz and 500 MHz are not supported on the
platform. See note regarding cfg_platform_freq in
configuration pin that is related to platform frequency.

This section describes the thermal specifications of the MPC8640.
Freescale Semiconductor
FIFO TX/RX clock frequency ≤ platform clock frequency ÷ 4.2
For example, if the platform frequency is 500 MHz, the FIFO Tx/Rx clock frequency should be no
more than 119 MHz.
FIFO TX/RX clock frequency ≤ platform clock frequency ÷ 3.2
For example, if the platform frequency is 500 MHz, the FIFO Tx/Rx clock frequency should be no
more than 156 MHz.
