State-Configurable Timer (SCT)
The state configurable timer can perform basic 16-bit and 32-bit timer/counter functions
with match outputs and external and internal capture inputs. In addition, the SCT can
employ up to two different programmable states, which can change under the control of
events, to provide complex timing patterns.
All inputs and outputs of the SCT are movable functions and are assigned to pins through
the switch matrix.
8.15.1 Features
• Two 16-bit counters or one 32-bit counter.
• Counters clocked by bus clock or selected input.
• Up counters or up-down counters.
• State variable allows sequencing across multiple counter cycles.
• The following conditions define an event: a counter match condition, an input (or
output) condition, a combination of a match and/or and input/output condition in a
specified state, and the count direction.
• Events control outputs, interrupts, and the SCT states.
– Match register 0 can be used as an automatic limit.
– In bi-directional mode, events can be enabled based on the count direction.
– Match events can be held until another qualifying event occurs.
• Selected events can limit, halt, start, or stop a counter.
• Supports:
– 4 inputs
– 4 outputs
– 5 match/capture registers
– 6 events
– 2 states
8.16 Multi-Rate Timer (MRT)
The Multi-Rate Timer (MRT) provides a repetitive interrupt timer with four channels. Each
channel can be programmed with an independent time interval, and each channel
operates independently from the other channels.
8.16.1 Features
• 31-bit interrupt timer
• Four channels independently counting down from individually set values
• Repeat and one-shot interrupt modes
8.17 Windowed WatchDog Timer (WWDT)
The watchdog timer resets the controller if software fails to periodically service it within a
programmable time window.
