READ mode
The in-lock can be read by setting the R/W bit to 1.
Notes
1. POR = Power On Reset. POR is internally set to 1 in case V
2. FL = In-lock flag; FL = 1: loop is phase-locked. The loop must be phase-locked during at least 8 periods of the internal
3. I2, I1 and I0 = digital information for I/O ports P2, P1 and P0 respectively.
4. A2, A1 and A0 = built-in 5-level A/D converter on the internal I/O port P6 (see Table “Digital AFC status”).
5. A = Acknowledge.
