Master SSP Module / Basic SSP Module Compatibility
Initialization
Example 17-2:
When changing from the SPI in the Basic SSP module, the SSPSTAT register contains two addi-
tional control bits. These bits are:
• SMP, SPI data input sample phase
• CKE, SPI Clock Edge Select
To be compatible with the SPI of the Master SSP module, these bits must be appropriately con-
figured. If these bits are not at the states shown in
occur.
