This is the read back register for
the enable manual override
defined in registers h262 and
h263.
Bit 0 enables/disables the phase
recovery. If bit 1 is set the rotation
is fixed and determined by bits
10:4. The rotation is specified as
a fraction of 2?.
271 REG_KS1 R/W 2:0 Phase recovery prop. gain h0000 Proportional gain of the phase
recovery:
0 = 8 * 2-10
1 = 16 * 2-10
2 = 32 * 2-10
3 = 64 * 2-10
4 = 128 * 2-10
5 = 256 * 2-10
6 = 512 * 2-10
