The SPFREQ command lets you set the frequency of the SPI slave input clock. If the SPI is configured for the slave mode, this command lets you enter the number of cycles <n> per one input clock period. If no value is given, a window appears and you are prompted for a value. If this command is not used, then the clocking is assumed to be set by the SPI control register.
>gdi SPFREQ [<n>]
Where: <n> The number of cycles for the period of the input clock.
>gdi SPFREQ 8
Set the period of the input slave clock to 8 cycles (total shift = 8*8 cycles per bit = 64 cycles).
