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
Refer to
• 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 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 interrupt
event 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
• Bit 5 - TX_AUTO_CRC_ON
Refer to
• Bit 4 - RX_BL_CTRL
Refer to
• Bit [3:2] - SPI_CMD_MODE
Refer to
• Bit 1 - IRQ_MASK_MODE
The AT86RF231 supports polling of interrupt events. Interrupt polling can be enabled by register
bit IRQ_MASK_MODE. Even if an interrupt request is masked by the corresponding bit in regis-
ter 0x0E (IRQ_MASK), the event is indicated in register 0x0F (IRQ_STATUS).
