43 / 126 page ![]() L9803 On-Chip Peripherals 43/126 The timer clock depends on the clock control bits of the CR2 register, as illustrated in Table 9: Clock Control Bits. The value in the counter register repeats every 131072, 262144 or 524288 CPU clock cycles depending on the CC[1:0] bits. The timer frequency can be f CPU/2, fCPU/4, fCPU/8 or an external frequency.
