Reserved. In normal functional mode, these bits MUST be set to zero.
19.44MHz Frame Pulse Output Enable. (For FPo_OFF2 only)
This bit is a reserved bit for FPo_OFF0 and FPo_OFF1, and MUST be set to zero.
When this bit is high, FPo_OFF2 is negative frame pulse output corresponding to
19.44MHz without channel offset.
When this bit is low, FPo_OFF2 is output frame pulse with channel offset.
FPo_OFF[n] Channel Offset
The binary value of these bits refers to the channel offset from original frame bound-
ary. Permitted channel offset values depend on bits 1-0 of this register.
FPo_OFF[n] Control bits.
