7.12.1.1 Features
7.12.1 State Configurable Timer (SCT) subsystem
7.12.2 General Purpose DMA (GPDMA)
7.12 AHB peripherals
The SCT allows a wide variety of timing, counting, output modulation, and input capture
operations. The inputs and outputs of the SCT are shared with the capture and match
inputs/outputs of the 32-bit general purpose counter/timers.
The SCT can be configured as two 16-bit counters or a unified 32-bit counter. In the
two-counter case, in addition to the counter value the following operational elements are
independent for each half:
In the two-counter case, the following operational elements are global to the SCT, but the
last three can use match conditions from either counter:
The DMA controller allows peripheral-to memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
