0x07: PKTCTRL1 – Packet Automation Control

Bit

Field Name

Reset

R/W

Description

7:5

PQT[2:0]

0 (0x00)

R/W

Preamble quality estimator threshold. The preamble quality estimator

increases an internal counter by one each time a bit is received that is

different from the previous bit, and decreases the counter by 8 each time

a bit is received that is the same as the last bit.

A threshold of 4·PQT for this counter is used to gate sync word detection.

When PQT=0 a sync word is always accepted.

Reserved

CRC_AUTOFLUSH

R/W

Enable automatic flush of RX FIFO when CRC in not OK. This requires

that only one packet is in the RXIFIFO and that packet length is limited to

the RX FIFO size.

APPEND_STATUS

R/W

When enabled, two status bytes will be appended to the payload of the

packet. The status bytes contain RSSI and LQI values, as well as CRC

OK.

1:0

ADR_CHK[1:0]

0 (00)

R/W

Controls address check configuration of received packages.

Setting

Address check configuration

0 (00)

No address check

1 (01)

Address check, no broadcast

2 (10)

Address check and 0 (0x00) broadcast

3 (11)

Address check and 0 (0x00) and 255 (0xFF)

broadcast
