nRF24LE1 Preliminary Product Specification
3.5.4
The RF Transceiver can send interrupts to the MCU. The interrupt (RFIRQ) is activated when TX_DS,
RX_DR or MAX_RT are set high by the state machine in the STATUS register. RFIRQ is deactivated when
the MCU writes '1' to the interrupt source bit in the STATUS register. The interrupt mask in the CONFIG reg-
ister is used to select the IRQ sources that are allowed to activate RFIRQ. By setting one of the mask bits
high, the corresponding interrupt source is disabled. By default all interrupt sources are enabled.
Revision 1.1
Note: The 3 bit pipe information in the STATUS register is updated during the RFIRQ high to low
Interrupt
transition. The pipe information is unreliable if the STATUS register is read during a RFIRQ
high to low transition.
