Digital-to-Analog Converter (DAC8B1CV1)
7.1 Introduction
The DAC8B1C is a 8-bit, 1-channel digital-to-analog converter module.
7.1.1 Features
The DAC8B1C includes these features:
• 8-bit resolution.
• One output independent monotonic channel.
7.1.2 Modes of Operation
The DAC8B1C functions the same in normal, special, and emulation modes. It has two low-power modes,
wait and stop modes.
7.1.2.1 Run Mode
Normal mode of operation.
7.1.2.2 Wait Mode
Entering wait mode, the DAC conversion either continues or aborts for low power, depending on the
logical state of the DACWAI bit.
7.1.2.3 Stop Mode
The DAC8B1C module is disabled in stop mode for reduced power consumption. The STOP instruction
does not affect DAC register states.
7.1.3 Block Diagram
Figure 7-1 illustrates the functional block diagram of the DAC8B1C module.
