• Manufacturer Part Number: si4430
• Description: Si4430 Ism Transceiver
• Manufacturer: Silicon Laboratories

Register 29h. Antenna Diversity 2
Register 2Ah. AFC Limiter
Register 2Bh. AFC Correction (LSBs)
Si4430
Reset value = 00000000
Reset value = 00101010
For the following registers (addresses 2Bh and 2Ch), use the following equation:
where Rb's unit is in kHz and “enmanch” is the Manchester Enable bit (found at address 71h bit [1]).
Therefore, the minimal data rate that this register can support without Manchester is 0.366 kbps.
Reset value = 00101011
