The PH2 bus clock feeds four primary divider chains. The functions
supplied by each of these chains are:
The SPI prescale factor is determined by bits SPR[2] in the system
configuration options 2 (OPT2) register and SPR[1:0] in the serial
peripheral control register (SPCR). See
Register
The input capture and output compare functions are based on a 16-bit
free-running counter, which is driven by the PH2 clock divided by a
programmable prescaler. Bits PR[1:0] of the timer interrupt mask 2
(TMSK2) register enable the user to select one of four divisors: 1, 4, 8,
or 16. The output of this prescaler, referred to as the main timer, feeds
the divider chains for the pulse accumulator, RTI, and COP circuits as
well as the free-running counter.
