FSK/OOK Description

RegIrqFlags1

(0x3e)

ModeReady

Set when the operation mode requested in Mode, is ready

- Sleep: Entering Sleep mode

- Standby: XO is running

- FS: PLL is locked

- Rx: RSSI sampling starts

- Tx: PA ramp-up completed

Cleared when changing the operating mode.

RxReady

Set in Rx mode, after RSSI, AGC and AFC.

Cleared when leaving Rx.

TxReady

Set in Tx mode, after PA ramp-up.

Cleared when leaving Tx.

PllLock

Set (in FS, Rx or Tx) when the PLL is locked.

Cleared when it is not.

Rssi

rwc

Set in Rx when the RssiValue exceeds RssiThreshold.

Cleared when leaving Rx or setting this bit to 1.

Timeout

Set when a timeout occurs

Cleared when leaving Rx or FIFO is emptied.

PreambleDetect

rwc

Set when the Preamble Detector has found valid Preamble.

bit clear when set to 1

SyncAddressMatch

rwc

Set when Sync and Address (if enabled) are detected.

Cleared when leaving Rx or FIFO is emptied.

This bit is read only in Packet mode, rwc in Continuous mode

RegIrqFlags2

(0x3f)

FifoFull

Set when FIFO is full (i.e. contains 66 bytes), else cleared.

FifoEmpty

Set when FIFO is empty, and cleared when there is at least 1 byte

in the FIFO.

FifoLevel

Set when the number of bytes in the FIFO strictly exceeds

FifoThreshold

, else cleared.

FifoOverrun

rwc

Set when FIFO overrun occurs. (except in Sleep mode)

Flag(s) and FIFO are cleared when this bit is set. The FIFO then

becomes immediately available for the next transmission /

reception.

PacketSent

Set in Tx when the complete packet has been sent.

Cleared when exiting Tx

PayloadReady

Set in Rx when the payload is ready (i.e. last byte received and

CRC, if enabled and CrcAutoClearOff is cleared, is Ok). Cleared

when FIFO is empty.

CrcOk

Set in Rx when the CRC of the payload is Ok. Cleared when FIFO

is empty.

LowBat

rwc

Set when the battery voltage drops below the Low Battery

threshold. Cleared only when set to 1 by the user.
