In the datasheet, in every instance where a register is described in 
detail, showing the bit assignments for all 8 bits, you'll find 
information about each bit's "Initial Value".  This tells you what the 
state of the register bit will be immediately after a reset.  In turn, 
the state of a periperal's control register bits will govern its 
initial state.

As long at that initial state is suitable for your application, you 
needn't do anything more.
