The wiring of the radio and the ATmega is shown below:

     AVR      RF230
     ---      -----
     PB4  -->  SLPTR
     PE5  <--  IRQ (INT5)
     PA7  -->  RSTN
     PB0  -->  SS
     PB2  -->  MOSI
     PB3  <--  MISO
     PB1  -->  SCK
     XTAL1 <--  MCLK

Fuses/Locks:
    uracoli settings:
     LF: 0xe2 - 8MHz internal RC Osc.
     HF: 0x91 - without boot loader (0x11 for debugging)
     HF: 0x90 - with boot loader    (0x10 for debugging)
     EF: 0xff
     LOCK: 0xef - protection of boot section

    original settings
     LF: 0x62 - RC oscillator 1 MHz
     HF: 0x9c - JTAG enabled, ISP enabled, reset to bootloader,
                1024 words bootloader size
     EF: 0xff - no brownout

Bootloader:
    Start at byte=0x1e000, address=0xf000, size = 4096 instructions/ 8192 bytes

Host Interface: HIF_TYPE

Build Options

zgbt1281a2uart0 : Zigbit, using UART0 for HIF (ISP pins!)
zgbt1281a2uart1 : Zigbit, using UART1 for HIF
zgbt1281a2nouart : Zigbit, no HIF

Define Documentation

#define HWTMR_PRESCALE (1)

UART0 is routed to the ISP pins, alternatively, UART1 can be used.

CS1[2:0] = 1 : Prescaler = 1
WGM1[3:0] = 0 : Mode = 4 : CTC operation

Timer is clocked at F_CPU, and TIMER_IRQ_vect is called every 65535 ticks.

#define LED_NUMBER (0)

number of LEDs for this board

#define TIMER_INIT ( )

Value:

do{ \
        TCCR1B |= (_BV(CS10));\
        TIMSK1 |= _BV(TOIE1); \
    }while(0)
