Figure 18.19 Operation Modes

(1)

Configuration Mode

This mode is entered after the module is released from reset. All required configuration fields in

the control register should be defined in this mode, before the SSI module is enabled by setting the

EN bit.

Setting the EN bit causes the module to enter the module enabled mode.

(2)

Module Enabled Mode

Operation of the module in this mode is dependent on the operation mode selected. For details,

refer to section 18.4.4, Transmit Operation and section 18.4.5, Receive Operation, below.
