3.5.40. PKT_CONFIG1
Summary: General packet configuration bits
Purpose:
General packet configuration bits.
Property: 0x1206
Default: 0
Fields:
PH_FIELD_SPLIT - default:0
0 = Field level properties (property 0x120D to 0x1220) are shared between TX and RX.
1 = Field level properties are split between TX and RX. TX: from 0x120D ~ 0x1220, RX: from 0x1221 ~ 0x1234
PH_RX_DISABLE - default:0
0 = Packet handler is enabled in RX.
1 = Packet handler is disabled in RX.
4FSK_EN - default:0
0 = The modem is not in 4FSK mode.
1 = The modem is in 4FSK mode.
RX_MULTI_PKT - default:0
0x0 = Turn off receive chain after packet received.
0x1 = Leave receive chain enabled after packet received.
MANCH_POL - default:0
0x0 = 0 is encoded/decoded to/from 01 Manchester pattern.
0x1 = 0 is encoded/decoded to/from 10 Manchester pattern.
CRC_INVERT - default:0
0x0 = Leave each CRC bit intact.
0x1 = Invert each CRC bit before transmit. Invert received CRC before comparison. Data in fifo remains untouched.
CRC_ENDIAN - default:0
0x0 = CRC low bytes are received/transmitted first.
0x1 = CRC high bytes are received/transmitted first.
BIT_ORDER - default:0
0x0 = Msb first for all fields. Bit 7 transmitted first timewise. Note: Preamble and sync word are always transmitted lsb
first.
0x1 = Lsb first for all fields. Bit 0 transmitted first timewise.
