Section 18 Serial Sound Interface (SSI)
18.4.3
There are three modes of operation: configuration, enabled and disabled. Figure 18.19 shows how
the module enters each of these modes.
(1)
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)
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.
