Timer/Counter Clock Sources
Reusing the Temporary High Byte Register
The following code examples show how to do an atomic write of the TCNT1 Register contents.
Writing any of the OCR1A/B or ICR1 Registers can be done by using the same principle.
Note:
The assembly code example requires that the r17:r16 register pair contains the value to be
written to TCNT1.
If writing to more than one 16-bit register where the high byte is the same for all registers writ-
ten, then the high byte only needs to be written once. However, note that the same rule of
atomic operation described previously also applies in this case.
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 (CS12:0)
bits located in the Timer/Counter control Register B (TCCR1B). For details on clock sources

Assembly Code Example
C Code Example
TIM16_WriteTCNT1:
void TIM16_WriteTCNT1(unsigned int i)
{
}
; Save global interrupt flag
in
; Disable interrupts
cli
; Set TCNT1 to r17:r16
sts
sts
; Restore global interrupt flag
out
ret
unsigned char sreg;
unsigned int i;
/* Save global interrupt flag */
sreg = SREG;
/* Disable interrupts */
_CLI();
/* Set TCNT1 to i */
TCNT1 = i;
/* Restore global interrupt flag */
SREG = sreg;
