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
Refer to
• Bit 5 - TX_AUTO_CRC_ON
Refer to
• Bit 4 - RX_BL_CTRL
If this register bit is set the Frame Buffer Empty Indicator is enabled. After sending a Frame Buf-
fer read command, refer to
microcontroller that an access to the Frame Buffer is not possible since valid PSDU data are
missing.
Pin IRQ does not indicate any interrupts during this time.
