System timers
The system timers provide two distinct types of system timer:
Periodic interrupts/triggers using the Peripheral Interrupt Timer (PIT)
Operating system task monitors using the System Timer Module (STM)
Peripheral Interrupt Timer (PIT)
The PIT provides five independent timer channels, capable of producing periodic interrupts
and periodic triggers. The PIT has no external input or output pins and is intended to be
used to provide system ‘tick’ signals to the operating system, as well as periodic triggers for
eQADC queues. Of the five channels in the PIT, four are clocked by the system clock, one is
clocked by the crystal clock. This one channel is also referred to as Real Time Interrupt
(RTI) and is used to wakeup the device from low power stop mode.
The following features are implemented in the PIT:
5 independent timer channels
Each channel includes 32-bit wide down counter with automatic reload
4 channels clocked from system clock
1 channel clocked from crystal clock (wake-up timer)
Wake-up timer remains active when System STOP mode is entered. Used to restart
system clock after predefined time-out period
Each channel can optionally generate an interrupt request or a trigger event (to trigger
eQADC queues) when the timer reaches zero
System Timer Module (STM)
defined by AUTOSAR (see http://www.autosar.org). It consists of a single 32-bit counter,
clocked by the system clock, and four independent timer comparators. These comparators
produce a CPU interrupt when the timer exceeds the programmed value.
The following features are implemented in the STM:
One 32-bit up counter with 8-bit prescaler
Four 32-bit compare channels
Independent interrupt source for each channel
Counter can be stopped in debug mode
1.3.19
Software Watchdog Timer (SWT)
The Software Watchdog Timer (SWT) is a second watchdog module to complement the
standard Power Architecture watchdog integrated in the CPU core. The SWT is a 32-bit
modulus counter, clocked by the system clock or the crystal clock, that can provide a system
reset or interrupt request when the correct software key is not written within the required
time window.
The following features are implemented:
32-bit modulus counter
Clocked by system clock or crystal clock
Optional programmable watchdog window mode
