8.22.2 Timer controlled subsystem

The timers, the analog components, and the DMA can be configured to form a subsystem

that can run independently of the main processor under the control of the SCTs and any

events that are generated by the A/D converters, the comparators, the SCT output

themselves, or the external pins. A/D conversions can be triggered by the timer outputs,

the comparator outputs or by events from external pins. Data can be transferred from the

ADCs to memory using the DMA controller, and the DMA transfers can be triggered by the

ADCs, the comparator outputs, or by the timer outputs.

For an overview of the subsystem, see Figure 13 “Subsystem with timers, switch matrix,

DMA, and analog components”.
