Overview

–

may be read with either ADC



Decimation Filter

–

Programmable decimation factor (2 to 16)

–

Selectable IIR or FIR filter

–

Up to 4th order IIR or 8th order FIR

–

Programmable coefficients

–

Saturated or non-saturated modes

–

Programmable Rounding (Convergent; Two’s Complement; Truncated)

–

Pre-fill mode to pre-condition the filter before the sample window opens



Full duplex synchronous serial interface to an external device

–

Free-running clock for use by an external device

–

Supports a 26-bit message length



Priority based Queues

–

Supports six Queues with fixed priority. When commands of distinct Queues are

bound for the same ADC, the higher priority Queue is always served first

–

Queue_0 can bypass all prioritization, buffering and abort current conversions to

start a Queue_0 conversion a deterministic time after the queue trigger

–

Streaming mode operation of Queue_0 to execute some commands several times

–

Supports software and hardware trigger modes to arm a particular Queue

–

Generates interrupt when command coherency is not achieved



External hardware triggers

–

Supports rising edge, falling edge, high level and low level triggers

–

Supports configurable digital filter



Supports four external 8-to-1 muxes which can expand the input channels to 56

channels total

DSPI

The Deserial Serial Peripheral Interface (DSPI) block provides a synchronous serial

interface for communication between the SPC563Mxx MCU and external devices. The

DSPI supports pin count reduction through serialization and deserialization of eTPU and

eMIOS channels and memory-mapped registers. The channels and register content are

transmitted using a SPI-like protocol. This SPI-like protocol is completely configurable for

baud rate, polarity and phase, frame length, chip select assertion, etc. Each bit in the frame

may be configured to serialize either eTPU channels, eMIOS channels or GPIO signals. The

DSPI can be configured to serialize data to an external device that supports the

Microsecond Channel protocol. There are two identical DSPI blocks on the SPC563Mxx

MCU. The DSPI output pins support 5 V logic levels or Low Voltage Differential Signalling

(LVDS) according to the Microsecond Channel specification.
