The ZNEO features a 4-channel DMA for efficient transfer of data between peripherals
and/or memories. The DMA controller supports data transfers to and from both internal
and external devices.
The ZNEO features a flexible PWM module with three complementary pairs or six
independent PWM outputs supporting deadband operation and fault protection trip input.
These features provide multiphase control capability for a variety of motor types and ensure
safe operation of the motor by providing immediate shutdown of the PWM pins during
Fault condition.
Three 16-bit reloadable timers are used for timing/counting events and PWM signal
generation. These timers provide a 16-bit programmable reload counter and operate in
ONE-SHOT, CONTINUOUS, GATED, CAPTURE, COMPARE, CAPTURE and
COMPARE, and PWM modes. The PWM function provides two complementary output
signals with programmable dead-time insertion.
The ZNEO products support three levels of programmable interrupt priority. The interrupt
sources include internal peripherals, GPIO pins, and system fault detection.
The on-chip crystal oscillator features programmable gain to support crystals and ceramic
resonators from 32 kHz to 20 MHz. The oscillator is also used with external RC networks
or clock drivers.
The ZNEO is reset using the RESET pin, POR, WDT, Stop Mode Recovery, or VBO
warning signal. The bidirectional RESET pin also provides a system RESET output
indicator.
The ZNEO Z16F Series features an integrated OCD. The OCD provides a rich-set of
debugging capabilities, such as reading and writing memory, programming the Flash,
setting breakpoints, and executing code. A single-pin interface provides communication to
the OCD.
