P2CVAL<7:0>: P2 Value bits
These bits indicate the value in P2 counter to generate carrier frequencies in FSK mode.
P2CVAL<7:0> = 0x62 (default)
P2CVAL is activated if RPS = 1 in GCONREG. Also default values R2, P2 and S2 generate 920 MHz
in FSK Mode.
S2CVAL<7:0>: S2 Value bits
These bits indicate the value in S2 counter to generate carrier frequencies in FSK mode.
S2CVAL<7:0> = 0x32 (default).
S2CVAL is activated if RPS = 1 in GCONREG. Also default values R2, P2 and S2 generate 920 MHz
in FSK Mode.
