The MSSP 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 SSPADD register (Register 22-6).
When a write occurs to SSPBUF, 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 Figure 22-36 triggers the
value from SSPADD to be loaded into the BRG counter.
This occurs twice for each oscillation of the module
