Overview about the Pin Strapping
Pin Strapping is used
Always
Only in SCI interface mode Defines the six LBSs of the SCI source address, see

Pin Strapping Function
Defines the used micro controller interface
Chapter 3.5.2.1
Programs the parameters N and M of the PLL in the
master clocking unit instead of registers GCM5 and
GCM6, see
- D(15:11) values programs PLL dividing factor M
- D(10:5) values programs PLL dividing factor N
Programming by pin strapping is equivalent to
programming by register bits GCM5.PLL_M(4:0) and
GCM6.PLL_N(5:0) which is used in asynchronous micro
controller modes.
