insertion, and separate top and bottom output polarity control. The up-counter value is programmable to
support a continuously variable PWM frequency. Both edge- and center-aligned synchronous pulse width
control (0% to 100% modulation) are supported. The device is capable of controlling most motor types:
ACIM (AC Induction Motors), both BDC and BLDC (Brush and Brushless DC motors), SRM and VRM
(Switched and Variable Reluctance Motors), and stepper motors. The PWMs incorporate fault protection
with sufficient output drive capability to directly drive standard opto-isolators. A “smoke-inhibit”,
write-once protection feature for key parameters is also included. The PWM is double-buffered and
includes interrupt control to permit integral reload rates to be programmable from 1 to 16. The PWM
modules provide a reference output to synchronize the Analog-to-Digital Converters.
The 56F802 incorporates two 12-bit Analog-to-Digital Converters (ADCs) with a total of five channels.
A full set of standard programmable peripherals is provided that include a Serial Communications
Interface (SCI), and two Quad Timers. Any of these interfaces can be used as General-Purpose
Input/Outputs (GPIO) if that function is not required. An on-chip relaxation oscillator eliminates the need
for an external crystal.
