Via pin IRQ, the transceiver signals different operating conditions to a connected micro-
controller. If a specific operating condition occurs, pin IRQ is set to high level.
If an interrupt occurs it is recommended to delete the interrupt be immediately deleted
by reading the status register, thus the next possible interrupt doesn’t get lost. If the
Interrupt pin doesn’t switch to low level by reading the status register the interrupt was
triggered by the RX/TX data buffer. In this case read or write the RX/TX data buffer
according to Table 42.

Events During TX Operation (T_MODE = 0)
4, 8 or 12 Bytes are in the TX data buffer or
the TX data buffer is empty (depends on
IR0 and IR1 in control register 1).
Events During RX Operation (T_MODE = 0)
4, 8 or 12 received bytes are in the RX data
buffer or a receiving error is occurred
(depends on IR0 and IR1 in control
register 1).
