Counters in 8051
WebThe 2nd chapter deals with the special function registers, their functions and its operation. Assembly language programming, instruction set, addressing modes, development tools & ALP programs are discussed in the 3rd chapter. Chapter 4 gives the details of 8051 timer/counters and its related SFRs- TCON & TMOD. WebApr 15, 2024 · C/T: These timers can be used as both timers and counters to keep time and to count external events. To use it as a timer, the C/T bit is set to 0, whereas it is set to 1 if it needs to be used as a counter of events. M0 and M1: there are four modes that 8051 offers. This means that we need two bits to set these modes.

WebMay 15, 2024 · 8051 Microcontroller has two 16-bit counters/timers: timer 0 and timer1.This timer work as a counter also. It means these timers perform dual function. When they work as a timer they generate time delay or when they work as counter they count events happening outside the microcontroller. Both timers are 16 bits wide. WebThe 8051 microcontroller has 2 timers/counters called T0 and T1. As their names suggest, their main purpose is to measure time and count external events. Besides, they can be used for generating clock pulses to be used in serial …
WebThe Program Counter (PC) is a 2-byte address which tells the 8051 where the next instruction to execute is found in memory. When the 8051 is initialized PC always starts at 0000h and is incremented each time an instruction is executed. It is important to note that PC isn’t always incremented by one.
