/* Save global interrupt flag */

sreg = SREG;

/* Disable interrupts */

_CLI();

/* Set TCNT1 to i */

TCNT1 = i;

/* Restore global interrupt flag */

SREG = sreg;

}

Note:

1. The example code assumes that the part specific header file is included. For I/O

Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and

“SBI” instructions must be replaced with instructions that allow access to extended

I/O. Typically “LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.

16.6.1. Reusing the Temporary High Byte Register

If writing to more than one 16-bit register where the high byte is the same for all registers written, the high

byte only needs to be written once. However, the same rule of atomic operation described previously also

applies in this case.

16.7. Timer/Counter Clock Sources

The Timer/Counter can be clocked by an internal or an external clock source. The clock source is

selected by the Clock Select logic which is controlled by the Clock Select bits in the Timer/Counter control
