Application Note
Whose Fault is It
AN1712
MOTOROLA
13
It is even more frustrating if the offending fault has disappeared by the
time the software responds. This may not foster feelings of harmony and
good will between the software and hardware engineers.
To simplify the hardware design task, the 'MP16 has four fault inputs that
are connected directly to the PWM module to immediately disable its
outputs. These inputs are evenly split into two banks that can be
programmed to disable different PWM outputs. This allows the 'MP16 to
control up to two independent power stages, each with their own fault
feedback signals. Examples of this are presented later.
The software engineer will appreciate the fact that each fault input has
its own interrupt vector, allowing a separate interrupt service routine to
be executed for each fault condition without having to poll separate
input/output (I/O) inputs to determine what caused the fault. In addition,
the CPU is capable of reading the immediate status of the fault inputs via
the FPINx bits in the fault status register (FSR).
All fault inputs work identically in terms of how they disable the PWM
outputs. When a fault occurs, the corresponding PWM outputs are
disabled immediately. When and how they become enabled again is
dependent on which operating mode is in effect for that fault input. Each
input can be programmed to work in either manual mode or automatic
mode, both of which are described in this application note.
Take Control
in Manual Mode
In manual mode, the software is responsible for reactivating the PWM
outputs. However, when this mode is selected, the odd numbered fault
inputs work differently than the even numbered inputs. For an odd
numbered fault, the affected PWMs will be reactivated on the next PWM
cycle after the software has acknowledged the fault by clearing the
associated FTACK bit in the FTACK register. The software assumes full
responsibility for PWM enabling, and the PWMs will come back on line
even if the fault is still asserted. This is useful for processing faults that
may have a long time constant or hysteresis associated with them, but
the PWM outputs are still required to be active during the time it takes
the fault signal to negate.
