Lect 35 Part 3 Timer and Counter Programming in 8051 ( Mode 2)

Lecture 35 (Part 3) continues with Timer and Counter Programming in 8051, focusing on Mode 2 operation of Timer 0. Mode 2, also known as the 8-bit auto-reload mode, is particularly useful for generating repetitive delays or tasks. This lecture covers configuring TMOD for Timer 0 in Mode 2, using interrupts for efficient handling, and writing Embedded C programs to implement these features. The session also discusses delay calculations and the use of the ISR (Interrupt Service Routine) with the appropriate vector address.

Key topics include:

TMOD Register for Timer 0 in Mode 2: Configuration and use cases.
8-Bit Auto-Reload Mode: How Mode 2 works and its benefits for repetitive tasks.
Delay Generation in Mode 2: Calculating and implementing precise delays.
Interrupt Handling with Timer 0: Configuring interrupts for Mode 2 operation.
ISR for Timer 0: Writing interrupt service routines specific to Mode 2.
Vector Address for Timer 0: Understanding the correct vector address for interrupts.
Embedded C Programming for Mode 2: Practical code examples for auto-reload functionality.
