5.2. Status Registers
AT88RF1354 contains three read-only registers that provide status information. The operational status of the IC is
contained in the SREG Register; by reading this register it can be determined if the RF Field is on and if the analog
circuits are fully powered up. The RF communication errors flags are stored in EREG; these flags are also returned in
the response of RF communication commands.
The IDR Register contains the hardware ID revision of the die; all die manufactured with the same design contain
identical IDR Register values. If the die design is changed, then IDR is updated.
5.3. Configuration Registers
Three registers control the configuration of the receiver, transmitter, and CLKO pin. The gain and noise immunity of
the receiver is controlled by the RXC Register. The transmit power and modulation index are controlled by the TXC
Register. The PLL Register controls the CLKO pin frequency, the CLKO output enable, and standby mode control
bits.
