Table A- 34 Description of the bytes
11 Mode for writing the configuration data:
• 0x01 = communication reset, no configuration data
• 0x02 = no communication reset, configuration data to be sent
• 0x03 = communication reset, configuration data to be sent
• 0x80 = no communication reset, individual parameters
Number of bytes to be written
46 ... 239 Buffer for up to 32 KB configuration data. Data that exceeds 239 bytes is trans-
ferred in several blocks.
11 ... 13 Configuration data:
• If "CONFIG" = 1, 2 or 3,
the value = 0
• If "CONFIG" = 0,
the value = 240 in bytes 11 and 12
the value in byte 13 is then = 1 (RF68xR)
• If "CONFIG" = 4,
the value = 1035 in bytes 11 and 12
the value in byte 13 is then = 1 (RF68xR)
