The MSSP1 module has a Baud Rate Generator avail-
able for clock generation in both I
modes. The Baud Rate Generator (BRG) reload value
is placed in the SSP1ADD register
When a write occurs to SSP1BUF, the Baud Rate Gen-
erator will automatically begin counting down.
Once the given operation is complete, the internal clock
will automatically stop counting and the clock pin will
remain in its last state.
An internal signal “Reload” in
value from SSP1ADD to be loaded into the BRG
counter. This occurs twice for each oscillation of the
