possible using P1CR[FSM]. This allows either the port 0 or port 1 timing to be used to generate the 2-KHz
super frame sync interrupt. The SFSC block then divides this accordingly. When P1CR[FSM] is set, FSC1
is the source of the super frame sync. In case P1CR[MS] is 0 (that is, port 1 is in slave mode), the interrupt
is ultimately driven by an external source. In case the M/S bit is 1 (that is, port 1 is in master mode), FSC1
ultimately comes from port 0.
