Bits 5 to 2: Input Clock Valid Control (IC[6:3]). These control bits can be used to force input clocks to be
considered invalid. If a clock is invalidated by one of these control bits it will not appear in the priority table in the
PTAB1 and PTAB2 registers, even if the clock is otherwise valid. These bits are useful when system software
needs to force clocks to be invalid in response to OAM commands. Note that setting a VALCR bit low has no effect
on the corresponding bit in the VALSR registers. See Sections 7.6.2.
0 = Force invalid
1 = Do not force invalid; determine validity normally

Bit 0: Input Clock Valid Control (IC9). This bit has the same behavior as the bits in VALCR1 but for the IC9 input
clock.
