115 / 282 page  115 7728D–AVR–07/09 ATtiny87/ATtiny167 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: 1. The example code assumes that the part specific header file is included. The assembly code example requires that the r17:r16 register pair contains the value to be written to TCNT1. 12.3.2 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 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. 12.4 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 (CS12:0) bits located in the Timer/Counter control Register B (TCCR1B). For details on clock sources and prescaler, see “Timer/Counter1 Prescaler” on page 107. Assembly Code Example (1) TIM16_WriteTCNT1: ; Save global interrupt flag in r18,SREG ; Disable interrupts cli ; Set TCNT1 to r17:r16 sts TCNT1H,r17 sts TCNT1L,r16 ; Restore global interrupt flag out SREG,r18 ret C Code Example (1) void TIM16_WriteTCNT1(unsigned int i) { 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; } |
