![]() In this example the PIC16F877A microcontroller runs with 4MHz crystal oscillator. This is a simple example which uses Timer2 interrupt to make an LED connected to RB0 blinking at a frequency of 1Hz. Timer2 can be shut-off by clearing control bit, TMR2ON (T2CON), to minimize power consumption. The match output of TMR2 goes through a 4-bit postscaler (which gives a 1:1 to 1:16 scaling inclusive) to generate a TMR2 interrupt (latched in flag bit, TMR2IF (PIR1)). The PR2 register is initialized to FFh upon Reset. The App Store has a wide selection of Games apps for your iOS device. Timer2 increments from 00h until it matches PR2 and then resets to 00h on the next increment cycle. Browse and download Games apps on your iPad, iPhone or iPod touch from the App Store.

The input clock (FOSC/4) has a prescale option of 1:1, 1:4 or 1:16, selected by control bits Is readable and writable and is cleared on any device Reset. It can be used as the PWM time base for the PWM mode of the CCP module(s). Timer2 is an 8-bit timer with a prescaler and a postscaler.
