Table 1 Bit allocation
Notes
1. In normal operation, 32 bits are programmed into the register.
2. bits b31 to b20 and b17 to b15 are test bits and must always be programmed as described in table 1.
3. Bit b19 defines the transmit rampup mode (see Table 6)
4. Bit b18 defines the dc extraction mode (see Table 5).
5. Bit b7 is the MSB of the frequency control word composed of (b7, b6, b5, b4, b3, b2, b1 and b0).
6. ref: bits ‘ref1’ and ‘ref0’ define the reference frequency (see Table 3).
7. pwr: bits, ‘pwr2’, ‘pwr1’ and ‘pwr0’ define the the typical output power (see Table 4).
8. pll: bit ‘pll’ = 1 forces the synthesizer PLL to remain on during the entire (TX or RX) slot.
9. trx: bit ‘trx’ = 1 forces the IC into RX mode.
10. The RF frequency is equal to 2304 + d[b7:b0] (see Table 2).
