RF1A Module

Functional

Function

FIFO Radio Core Interrupt may be triggered independent of the RFINx condition being met

Description

The radio core interrupt flags (RFIFGx) may be set and could generate a radio core interrupt although the corresponding radio input (RFINx) signal condition has not been met.

This is true for the FIFO Mapped Control Signals RFIFG3, RFIFG4, RFIFG5, RFIFG6, RFIFG7, RFIFG8, RFIFG9 (negative edge), and RFIFG10 (negative edge).

Workaround

When handling the radio core interrupts RFIFG3 - RFIFG10, proceed with the ISR only after verifying that the RFINx signal respective to the RFIFGx flag is active.
