19.2.1 Operating Mode Selection
The operating mode of the SSC module is controlled by its control register SSCx_CON.
This register has a double function:
• During programming (SSC disabled by SSCx_CON.EN = 0), it provides access to a
set of control bits
• During operation (SSC enabled by SSCx_CON.EN = 1), it provides access to a set
of status flags
In the following, the layout of register CON is shown for both functions.
