ECE 3430 – Intro to Microcomputer Systems ECE 3430 – Introduction to Microcomputer Systems University of Colorado at Colorado Springs Lecture #15 Agenda Today: More on the Timer_A timer block Lecture #15 ECE 3430 – Intro to Microcomputer Systems Fall 2014

ECE 3430 – Intro to Microcomputer Systems Timer_A Timer Block The 16-bit timer (TAR) can count up to a threshold and then roll over to zero or start counting back down to 0. Refer to the Timer_A section of the MSP430x2xx Family User Guide for exhaustive details on the Timer_A block. Input Capture/Output Compare blocks (channels) are part of the Timer_A block. These allow us to extend the use of the basic timer block by involving input and output pins. We’ll discuss this after exam 2. The specific interrupt vectors and input/output pins involved are device-specific and, hence, can be found in the device-specific datasheets. All capture/compare blocks share a common timer block (only one TAR). Lecture #15 ECE 3430 – Intro to Microcomputer Systems Fall 2014
