FP19EN
19.44 MHz 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
19.44 MHz 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.
1 - 0
FOF[n]C1 - 0
FPo_OFF[n] Control bits
Note: [n] denotes output offset frame pulse from 0 to 2.
