Register 0x0F (IRQ_STATUS):
The IRQ_STATUS register contains the status of the pending interrupt requests.
Table 4-17. Register 0x0F (IRQ_STATUS)
By reading the register after an interrupt is signaled at pin 24 (IRQ), the source of the
issued interrupt can be identified. A read access to this register resets all interrupt bits,
and so clears the IRQ_STATUS register.
If register bit IRQ_MASK_MODE (register 0x04, TRX_CTRL_1) is set, an interrupt
event can be read from IRQ_STATUS register, even if the interrupt itself is masked;
refer to Figure 4-18. However, in that case no timing information for this interrupt is
provided. It is recommended to read the interrupt status register 0x0F (IRQ_STATUS)
first to clear the history.
Register 0x04 (TRX_CTRL_1):
The TRX_CTRL_1 register is a multi purpose register to control various operating
modes and settings of the radio transceiver.
Table 4-18. Register 0x04 (TRX_CTRL_1)
• Bit 7 – PA_EXT_EN
RX/TX Indicator, refer to section 9.4.3.
• Bit 6 – IRQ_2_EXT_EN
The timing of a received frame can be determined by a separate pin. If register bit
IRQ_2_EXT_EN is set to 1, the reception of a PHR field is directly issued on
pin 10 (DIG2), similar to interrupt IRQ_2 (RX_START). Note that this pin is also active,
even if the corresponding IRQ_2 (RX_START) mask bit in register 0x0E (IRQ_MASK)
is set to 0. The pin remains at high level until the end of the frame receive procedure.
For further details refer to section 9.5.
