The Timer2/3 module is a 32-bit timer (which can be
configured as two 16-bit timers) with selectable
operating modes. These timers are used by other
peripheral modules, such as:
• Input Capture
• Output Compare/Simple PWM
Timer2/3 has the following modes:
• Two independent 16-bit timers (Timer2 and
• Single 32-bit timer operation
• Single 32-bit synchronous counter
Further, the following operational characteristics are
supported:
• ADC conversion start trigger
• 32-bit Timer gated by external pulse
• Selectable prescaler settings
• Timer counter operation during Idle and Sleep
• Interrupt on a 32-bit period register match
9.2.3
The Timer4/5 module is similar in operation to the
Timer2/3 module. Differences include:
• The Timer4/5 module does not support the ADC
• Timer 4/5 can not be used by other peripheral

The Motor Control PWM (MCPWM) module simplifies
the task of generating multiple, synchronized pulse
width modulated outputs. In particular, the following
power and motion control applications are supported:
• Three-Phase AC Induction Motor
• Switched Reluctance (SR) Motor
• Brushless DC (BLDC) Motor
• Uninterrupted Power Supply (UPS)
The PWM module has the following features:
• Dedicated time base supports T
• Two output pins (pair) for each PWM generator
• Complementary or independent operation for
• Hardware dead-time generators for
• Output pin polarity defined by nonvolatile device
• Multiple output modes:
• Manual override register for PWM output pins
• Hardware Fault input pins with programmable
• Trigger for synchronizing A/D samples and
• Each output pin associated with the PWM can be

There are two versions of the MCPWM module
depending on the dsPIC30F device that is selected.
There is an 8-output module that is typically found on
devices that have 64 or more pins. A 6-output MCPWM
module is also available and is typically found on
smaller devices that have fewer than 64 pins.
The 6-output MCPWM module is useful for single or
3-phase power application, while the 8 MCPWM can
support 4-phase motor applications. The 8-output
MCPWM (Figure 9-2) also provides increased flexibility
in an application because it supports two fault pins and
two programmable dead times.
