All timings specified with a capactive load of 25pF.
SSI_MCLK can be generated from SSI_CLKIN or a divided version of the internal system clock (SYSCLK).
SSI_BCLK can be derived from SSI_CLKIN or a divided version of SYSCLK. If the SYSCLK is used, the minimum
divider is 6. If the SSI_CLKIN input is used, the programmable dividers must be set to ensure that SSI_BCLK does not
exceed 4 x f
