IRQ_2_EXT_EN
Each SPI access can be configured to return status information of the radio transceiver
(PHY_STATUS) to the microcontroller using the first byte of the data transferred via MISO.
The content of the radio transceiver status information can be configured using register bits
SPI_CMD_MODE (register 0x04, TRX_CTRL_1). After reset, the content on the first byte send
on MISO to the microcontroller is set to 0x00.
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.
• Bit 7 - PA_EXT_EN

• Bit 6 - IRQ_2_EXT_EN
Refer to
• Bit 5 - TX_AUTO_CRC_ON
Refer to
• Bit 4 - RX_BL_CTRL
Refer to
• Bit [3:2] - SPI_CMD_MODE
Each SPI transfer returns bytes back to the SPI master. The content of the first byte can be con-
figured using register bits SPI_CMD_MODE. The transfer of the following status information can
be configured as follows:
