EdSim51 - Notes on the 8051 MOV TMOD, #02H ;initialize timer 0 as 8-bit auto-reload timer MOV TH0, #0CEH ;set timer 0 high-byte to produce 50us delay (assuming system clock frequency of 12MHz)
8051 Tutorial: Interrupts - 8052.com As you can see, each of the 8051s interrupts has its own bit in the IE SFR. You enable a given interrupt by setting the corresponding bit. For example, if you wish to enable Timer 1 Interrupt, you would execute either: MOV IE,#08h or SETB ET1 Both of the
EdSim51 - Example Programs - EdSim51 - The 8051 Simulator for Teachers and Students 4. LCD Module - logic diagram extract The example program for programming the LCD module is written in C. It was developed and compiled using the Keil uVision3 IDE. If you wish to write your own C programs for the 8051, get the free evaluation version of
INTERRUPT PRIORITY IN THE 8051/52 - what-when-how — In Depth Tutorials and Information When the 8051 is powered up, the priorities are assigned according to Table 11-3. From Table 11-3 we see, for example, that if external hardware interrupts 0 and 1 are ... ed to first. Only after INTO has been serviced is INT1 serviced, since INT1 has the

8051 Pulse Width Measurement Example - Keil Embedded Development Tools for ARM, Cortex-M, Cortex-R4, 8051 Pulse Width Measurement Example This example program shows how to compute the width of a pulse using timer0 in mode 1. Port 3.2 is used as an external gate for the timer. An interrupt is used to accumulate timer overflow. The width of each pulse is .
8051 Timer 0 Mode 1 Example Program - Keil This example program shows how to configure timer/counter 0 as a 16-bit timer. An interrupt service routine (ISR) is invoked each time the timer overflows (goes ...
-1- 8051 的中斷8051 共有五個中斷,可透過中斷致能暫存器(IE)設定 ... 若中斷設定致能,當中斷訊號產生時8051 會暫停目前工作跳至該中斷的中斷位址處 抓. 取程式碼執行, ... IE.5 (ET2):8052 才用到的Timer 2 中斷控制用,8051 未用。
