SSI Reset and Initialization Procedure
MOTOROLA
Synchronous Serial Interface (SSI)
30-45
The correct sequence to initialize the SSI is as follows:
1. Issue a power-on or SSI reset.
2. Set the SSI_EN bit in the SCSR.
3. Set all other control bits (such as TXDIR and RXDIR).
4. Set the TE and RE bits in the SCSR.
To ensure proper operation of the SSI, use the power-on or SSI reset before changing any of the control
bits listed in Table 30-24. These control bits should not be changed during SSI operation.
NOTE:
The SSI bit clock must go low for at least one complete period to ensure
proper SSI reset.
