26.4.4
There are three modes of operation: configuration, enabled and disabled. Figure 26.20 shows the
transition diagram between these operation modes.
(1)
This mode is entered after the module is released from reset. All required settings 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 SSI module to enter the module enabled mode.
(2)
Operation of the module in this mode depends on the selected operating mode. For details, see
section 26.4.5, Transmit Operation and section 26.4.6, Receive Operation.
