Texas Instruments MSP430x1xx Family User Manual

About this manual

This manual introduces the MSP430x1xx microcontroller family, covering its architecture, flexible clock system, embedded emulation, and memory organization. It describes the address space, flash/ROM, RAM, and the wide range of peripheral modules such as timers, watchdog, UART, and digital I/O.

Detailed sections explain system resets, interrupt handling, low‑power modes, and the operation of specific peripherals like the DAC12, hardware multiplier, and DMA controller. Register maps and bit‑field definitions are provided for each module, enabling developers to configure and program the devices effectively.

Frequently asked questions

How do you select the DAC12 resolution?

Set the DAC12RES bit: 0 selects 12‑bit resolution, 1 selects 8‑bit resolution.

What reference voltage options are available for the DAC12?

The DAC12 SREFx bits allow selection of VREF+ or VeREF+ as the reference voltage.

How is the DAC12 module enabled?

Set the DAC12ENC bit to 1 (or clear DAC12ENC to 0 to disable).
