The internal circuitry in the 8051 microcontrollers provides a clock source to the timer which is 1/12th of the frequency of crystal attached to the microcontroller, also called Machine cycle frequency. For example, suppose we have a crystal frequency of 11.0592 MHz then the microcontroller will provide 1/12th i.e. ______ clock frequency= (crystal Osc.frequency)/12 = (11.0592 MHz)/12 = 921.6 KHz. Period T= 1/ (921.6 kHz) =1.085 μS. TIMERS OF 8051- TIMER MODES MODE-0 (13-BIT TIMER MODE). Mode 0 is a 13-bit timer mode for which 8-bit of THx and 5-bit of TLx (as Prescaler) is used. It is mostly used for interfacing possible with old MCS-48 family microcontrollers. 8-bit of THx and lower 5-bit of TLx used to form a total 13-bit timer. Higher 3-bits of TLx should be written as zero while using timer mode0, or it will affect the result. In this mode the timer is used as 13-bit up counter. The 13bit value is between 0000H-1FFFH. The value is loaded into TL (5 bits) and TH(8 bits). When the timer reaches its maximum of 1FFFH it rolls over to 0000H and TF is raised. Here TLx will count from 0 to 31. When it in incremented from 31 it will reset to zero and increment THx. This effectively only 13 bit of timer is being used. The timer interrupt flag TFx is set when the timer rolls over from 1FFFH-0000H.
