DETAILS
R1CVAL<7:0>: R1 Value bits
These bits indicate the value in R1 counter to generate carrier frequencies in FSK mode.
R1CVAL<7:0> = 0x77 (default)
R1CVAL is activated if RPS = 0 in GCONREG. Also default values R1, P1 and S1 generate 915 MHz
in FSK Mode.
P1CVAL<7:0>: P1 Value bits
These bits indicate the value in P1 counter to generate carrier frequencies in FSK mode.
P1CVAL<7:0> = 0x64 (default)
P1CVAL is activated if RPS = 0 in GCONREG. Also default values R1, P1 and S1 generate 915 MHz
in FSK Mode.
