PIC24FJ16MC101/102 AND PIC24FJ32MC101/102/104
15.0 MOTOR CONTROL PWM
MODULE
Note 1: This data sheet summarizes the features
of the PIC24FJ16MC101/102 and
PIC24FJ32MC101/102/104 family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 47. âMotor Con-
trol PWMâ (DS39735), in the âPIC24F
Family Reference Manualâ, which is
available on the Microchip web site
(www.microchip.com).
2: It is important to note that the
specifications in Section 26.0 âElectri-
cal Characteristicsâ of this data sheet,
supercede any specifications that may be
provided in PIC24F Family Reference
Manual sections.
3: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 âMemory Organizationâ in
this data sheet for device-specific register
and bit information.
The PIC24FJ16MC101/102 and PIC24FJ32MC101/
102/104 devices have a 6-channel Pulse-Width
Modulation (PWM) module.
The PWM module has the following features:
⢠Up to 16-bit resolution
⢠On-the-fly PWM frequency changes
⢠Edge-Aligned and Center-Aligned Output modes
⢠Single Pulse Generation mode
⢠Interrupt support for asymmetrical updates in
Center-Aligned mode
⢠Output override control for Electrically
Commutative Motor (ECM) operation or BLDC
⢠Special Event comparator for scheduling other
peripheral events
⢠Fault pins to optionally drive each of the PWM
output pins to a defined state
⢠Duty cycle updates configurable to be immediate
or synchronized to the PWM time base
15.1 PWM1: 6-Channel PWM Module
This module simplifies the task of generating multiple
synchronized PWM outputs. The following power and
motion control applications are supported by the PWM
module:
⢠3-Phase AC Induction Motor
⢠Switched Reluctance (SR) Motor
⢠Brushless DC (BLDC) Motor
⢠Uninterruptible Power Supply (UPS)
This module contains three duty cycle generators,
numbered 1 through 3. The module has six PWM
output pins, numbered PWM1H1/PWM1L1 through
PWM1H3/PWM1L3. The six I/O pins are grouped into
high/low numbered pairs, denoted by the suffix H or L,
respectively. For complementary loads, the low PWM
pins are always the complement of the corresponding
high I/O pin.
