Configure SEC/FSC Port
The FSC pulse is generated if the DCO-R circuitry of the selected
channel is active (CMR2.IRSC = 1 or CMR1.RS(1:0) = 10 or 11).
SEC/FSC can be switched into tristate mode by setting SIC3.FSCT.
00 = SEC: Input, active high
01 = SEC: Output, active high
10 = FSC: Output, active high
11 = FSC: Output, active low

Outgoing RFM on pin RPx is active high for 488 ns independent
of the programmed system clock frequency.
Outgoing RFM on pin RPx is active high for one system clock
period as programmed by SIC.SSC.
