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
State variable
Limit, halt, stop, and start conditions
Values of Match/Capture registers, plus reload or capture control values

Inputs
Events
Outputs
Interrupts
Two 16-bit counters or one 32-bit counter.
Counter(s) clocked by bus clock or selected input.
Up counter(s) or up-down counter(s).
State variable allows sequencing across multiple counter cycles.
Event combines input or output condition and/or counter match in a specified state.
Events control outputs and interrupts.
Selected event(s) can limit, halt, start, or stop a counter.
Supports:
– up to 8 inputs (one input connected internally)
– up to 16 outputs
– 16 match/capture registers
– 16 events
– 32 states
