http://www.piclist.com/techref/microchip/timer.htm WebOct 3, 2013 · The TMR0 prescaler is set (via 4 bits in the OPTION register) to divide-by-1, -2, -4, -8, -16, -32, -64, -128, or -256. The TMR0 input clock (1 MHz in your case) is passed to the prescaler, whose divided-down output is then fed to the TMR0 register. For example, if the TMR0 prescaler is set to divide-by-4 and the PIC is running at 4 MHz, the ...

WebA prescaler is an electronic counting circuit used to reduce a high frequency electrical signal to a lower frequency by integer division. The prescaler takes the basic timer clock frequency (which may be the CPU clock frequency or may be some higher or lower frequency) and divides it by some value before feeding it to the timer, according to how the prescaler … WebFeb 12, 2024 · CPU Timer Module ¶.
