4.4.1 Register Description – SPI Control
4.5 Radio Transceiver Identification
8168C-MCU Wireless-02/10
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 4-4. Register 0x04 (TRX_CTRL_1)
• Bit 7 – PA_EXT_EN
Refer to section 9.4.3.
• Bit 6 – IRQ_2_EXT_EN
Refer to section 9.5.2.
• Bit 5 – TX_AUTO_CRC_ON
Refer to section 6.3.5.
• Bit 4 – RX_BL_CTRL
Refer to section 9.6.2.
• Bit 3:2 – SPI_CMD_MODE
Each SPI transfer returns bytes back to the SPI master. The content of the first byte can
be configured using register bits SPI_CMD_MODE.
Table 4-5. PHY Status Information
• Bit 1:0 – IRQ_MASK_MODE, IRQ_POLARITY
Refer to section 4.7.2.
The AT86RF212 can be identified by four registers. One register contains a unique part
number and one register the corresponding version number. Additional two registers
contain the JEDEC manufacture ID.
