REGISTER 5—SYNC BYTE REGISTER
Register 5—Sync Byte Register Comments
• Sync byte detect is enabled by programming Bits R4_DB [25:23] to 010 or 011.
• This register allows a 24-bit sync byte sequence to be stored internally. If the sync byte detect mode is selected, then the INT/LOCK pin
• The transmitter must transmit the MSB of the sync byte first and the LSB last to ensure proper alignment in the receiver sync byte
• Choose a sync byte pattern that has good autocorrelation properties.
goes high when the sync byte has been detected in Rx mode. Once the sync word detect signal has gone high, it goes low again after
nine data bits.
