(3) RX FIFO access error

If one of the following conditions is met, RX FIFO access error interrupt (INT[12]: group2) will be generated.

●RX data overflow occurs to RX_FIFO

●Read RX_FIFO during no data in the RX_FIFO

When RX FIFO acccess error interrupt occurs, issuing TRX_OFF after RX completion interrupt (INT[8]:

group2) is recognized, or issueing Force_TRX_OFF by [RF_STATUS:B0 0x0B] register without waiting for

RX completion interrupt. After that, issuing RX FIFO pointer clear by [STATE_CLR:B0 0x16] register and

clear remaining interrupts in the [INT_SOURCE_GRP2:B0 0x0E] register.
