## Detailed Description

This board is describes the Sensor Terminal Board from Dresden Electronic. It is a carrier board for the RCB family.

The Sensor Terminal Board is a carrier board 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
         PD6  <--  CLKM
         PD4  <--  IRQ (ICP1)
         PB5  -->  RSTN
         PB0  -->  SS
         PB2  -->  MOSI
         PB3  <--  MISO
         PB1  -->  SCK

        The STBxxx has memory mapped LEDS and Keys.
        KEY: PE5
        LEDS

    2 x memory mapped at 0x4000  (Option 1)
    3 x IO mapped at PE2:PE4 (Option 2)

        You can select between using the LEDs on the RCB or on the STB.
        In order to use the RCB LEDS, you have to define the macro USE_RCB_LEDS.

        The LEDs on STB have a write-only memory interface, so we can't read back the LED status.
        So we need to have a shadow register, which stores the current LED state.
        Since the board interface consists only of a header file, we use register
        GPIO2 on ATmega1281 for shadowing, because it would be hard to ensure the
        single instantiation of a global variable from a header file, which is used
        in many module files.

    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

    Original Settings w/ rdk231
         LF: 0x61
         HF: 0x91
         EF: 0xfe

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

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.
