AN3117
Application note
Using the STM8L05xxx/15xxx, STM8L162xx,
STM8AL31xx/3Lxx DMA controller
Note:
Introduction
This application note describes how to use the direct memory access (DMA) controller of
the STM8L05xxx/15xxx, STM8L162xx and STM8AL31xx/3Lxx devices. Table 1 shows the
STM8 products covered by this application note.
The DMA controller, the STM8™ core and the memory system contribute to provide a high
data bandwidth and to develop very low latency response time software.
This application note also describes how to take full advantage of these features and ensure
correct response times for different peripherals and subsystems.
All examples and explanations in this document are based on the STM8L05x/STM8L15x/
STM8L16x/STM8AL31x/STM8AL3Lx standard peripheral library and the SSTM8L05xx,
STM8L15xx, STM8L162x, STM8AL31xx and STM8AL3Lxx microcontroller family reference
manual (RM0031). Please check the available resources of your product when using the
examples shown in this document.
