LM3S3651 Datasheet, PDF (548/798 Pages) Texas Instruments – Stellaris® LM3S3651 Microcontroller

Synchronous Serial Interface (SSI)
Note that the SSI module clock must be enabled before the registers can be programmed (see
page 224). There must be a delay of 3 system clocks after the SSI module clock is enabled before
any SSI module registers are accessed.
Note: The SSI must be disabled (see the SSE bit in the SSICR1 register) before any of the control
registers are reprogrammed.
