## Detailed Description

This board is describes the STK541 that comes with Atmels ATAVRRZ541 Packet Sniffer Kit.

The Packet Sniffer Kit STK541 is a carrier board, which fits on top of a STK500 and is used for the radio controller board family. The transceiver wiring fits the common RCBs. The wiring of the radio and the ATmega is shown below:

         AVR      RF230
         ---      -----
         PB4  -->  SLPTR
         P??  <--  MCLK
         PD4  <--  IRQ (ICP1)
         PB5  -->  RSTN
         PB0  -->  SS
         PB2  -->  MOSI
         PB3  <--  MISO
         PB1  -->  SCK

        The STK541 has no LEDS and Keys, so we define the ressources
        from the  RCB230 here.

        KEY: PE5
        LEDS: PE2:PE4

        DBG: PD0 - connector X20:2 (ground X20:1)

    Fuses/Locks:
         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

#define TIMER_INIT | ( |  | ) |

Value:

    do{ \

            TIMSK1 |= _BV(TOIE1); \
        }while(0)

Intialization of the hardware timer T1 (16bit)

- 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.
