Hi All.

I tuned the registers according to the set frequency in TESEUS.
XTAL 13.56 MHz
out freq: 868.4 MHz
ISM - 2
PLL INT - 63
PLL FRAC 2: 1: 0 - 16 169 39
FRAC compensation 1
VAC FAST COUNTER - 256
But when I try to issue a signal, I get the status
PLL lock detector error

I tried different crystal oscillators, but as soon as the PLL value should give out the frequency in the selected ISM range, I get this error.
