#define CPU_WAIT

(

)

Wait for interupt (oscillator and core is running).

#define CPU_POWER_SAVE

(

)

Go to powersave. Oscillator and core is stopped. Only Async Timer 2 and Int0/Int1 can wake CPU.

#define CPU_IDLE

(

)

Go to idle (oscillator is running, core is sleeping).

#define CPU_PORTS_INIT

(

)

Init all port to input with enabled pull up to avoid current draw at power down.

#define CPU_INIT

(

)

Init CPU.

#define UART_WRITE_BYTE

(

_ch

)

Waits for the transmitter to be ready then outputs the character

#define UART_READ_BYTE

(

)

Waits until a character becomes available then sets
