BUFSTATUS

BUFSTATUS provides status for either the RX buffer or the TX buffer. If BUFSTATUS is referring to the TX buffer, once BUFSTATUS is set High it remains High until RESETN is activated. Else if BUFSTATUS is referring to the RX buffer, once BUFSTSTATUS is High it can be cleared using BUFSTATUS_RST. If BUFTATUS[6] is 0x1 the internal FIFO overflows and when the BUFSTATUS[5] is 0x1 the internal FIFO underflows. Available from version 17.5.a. For more information consult the transceiver user guide(search for RXBUFSTATUS/TXBUFSTATUS).
