PIC18F47J53 FAMILY
20.5.7.1
Because MSSP1 and MSSP2 are independent, they
can operate simultaneously in I
different baud rates. This is done by using different
BRG reload values for each module.

Because this mode derives its basic clock source from
the system clock, any changes to the clock will affect
both modules in the same proportion. It may be
possible to change one or both baud rates back to a
previous value by changing the BRG reload value.
