The wiring of the radio and the ATmega is shown below:
ATmega1281 AT86RF230
---------- ---------
PB1 --> SCK
PB2 <-- MOSI
PB3 --> MISO
PB0/PB4 --> SEL (you need to drive both pins)
PB5 --> SLP_TR
PB6 --> TRX_RESET
INT4/PE4 --> IRQ
XTAL2 <-- CLKM
PD0 --> KEY Interface
PD6:7 --> LED Interface
Fuses:
LF: 0xe2 - 8MHz internal RC Osc.
HF: 0x11 - without boot loader
HF: 0x10 - with boot loader
EF: 0xff
LOCK: 0xef - protection of boot section
Bootloader:
Start at byte=0x1e000, address=0xf000, size = 4096 instructions/ 8192 bytes
