7.4.3 STREAM RX TIMEOUT
The radio sets STRMIF to indicate that the time defined
in STRMTO register has elapsed.

STRMIF: Receive Stream Time-Out Error Interrupt Flag bit
Set by the device to indicate that the duration specified in STRMTO elapsed since the last received
packet while in RX-Streaming mode, and the MAC clears the stored sequence number.
Nonpersistent, cleared by SPI read.
Note 1: In Packet mode, use a single buffer for received frames. In RX-Streaming mode, use both buffers for recep-
tion.

STRMTO<15:0>: Stream Time-Out bits
The STRMTO<15:0> bits indicate the maximum number of allowed Base time units between the end of
one RX Stream packet and the successful reception of the next. If no RX Stream packet is successfully
received within this time, STRMIF is set.
