SSP Module / Basic SSP Module Compatibility
Initialization
Example 16-2: SPI Master Mode Initialization
When changing from the SSP Module to the Basic SSP module, the SSPSTAT register contains
two additional control bits. These bits are:
• SMP, SPI data input sample phase
• CKE, SPI Clock Edge Select
To be compatible with the SPI of the Basic SSP module, these bits must be appropriately config-
ured. If these bits are not at the states shown in
be expected. If the SSP module uses a different configuration then shown in
Basic SSP module can not be used to implement that mode. That mode may be implemented in
software.
