(2) Channel #0 frequency setting
TX frequency can be set by [TXFREQ_I: B1 0x1B], [TXFREQ_FH: B1 0x1C], [TXFREQ_FM: B1 0x1D]
and [TXFREQ_FL: B1 0x1E]. RX frequency can be set by [RXFREQ_I: B1 0x1F], [RXFREQ_FH: B1 0x20],
[RXFREQ_FM: B1 0x21] and [RXFREQ_FL: B1 0x22]. When enabling PLL 1/2 division mode by setting
PLL_MODE([PLL_DIV_SET:B1 0x1A(4)])=0b1, calcurated with fref =FMCK1/2 in the following formula.
Channel #0 frequency setting can be caluculated using the following formula.

I (Hex) is set to [TXFREQ_I: B1 0x1B], [RXFREQ_I: B1 0x1F] registers.
F (Hex.) is set to the following registers.
For TX, from MSB, set in order of [TXFREQ_FH: B1 0x1C], [TXFREQ_FM: B1 0x1D], [TXFREQ_FL:
B1 0x1E] registers.
For RX, from MSB, set in order of [RXFREQ_FH: B1 0x20], [RXFREQ_FM: B1 0x21], [RXFREQ_FL:
B1 0x22] registers.
