FSC
FSC Control Register : EFSCD (bit 2) = ‘1’, i.e. FSC rising edge is delayed in one cycle of 61.44 MHz (16 ns)
after DCL_2000 rising edge. Special mode designed for working with the VIP.

When a short-pulse FSC cycle is issued, FSC high period is one DCL (of IOM-2) cycle long. In the worst case,
when DCL_2000 = 3072 kHz and DCL = 4096 kHz, FSC high pulse is shorter than one cycle of DCL_2000,
but yet it is stable from the rising edge and until at least 70 ns after the falling edge of DCl_2000 within this
single cycle. Thus setup and hold times of FSC around DCL_2000’s falling edge are guaranteed.
