eTimer

The SPC560P34/SPC560P40 includes one eTimer module which provides six 16-bit

general purpose up/down timer/counter units with the following features:

●

Clock frequency same as that used for the e200z0h core

●

Individual channel capability

–

Input capture trigger

–

Output compare

–

Double buffer (to capture rising edge and falling edge)

–

Separate prescaler for each counter

–

Selectable clock source

–

0–100% pulse measurement

–

Rotation direction flag (quad decoder mode)

●

Maximum count rate

–

External event counting: max. count rate = peripheral clock/2

–

Internal clock counting: max. count rate = peripheral clock

●

Counters are:

–

Cascadable

–

Preloadable

●

Programmable count modulo

●

Quadrature decode capabilities

●

Counters can share available input pins

●

Count once or repeatedly

●

Pins available as GPIO when timer functionality not in use

1.5.26

Analog-to-digital converter (ADC) module

The ADC module provides the following features:

Analog part:

●

1 on-chip analog-to-digital converter

–

10-bit AD resolution

–

1 sample and hold unit

–

Conversion time, including sampling time, less than 1 µs (at full precision)

–

Typical sampling time is 150 ns minimum (at full precision)

–

DNL/INL ±1 LSB

–TUE < 1.5 LSB

–

Single-ended input signal up to 3.3 V/5.0 V

–

3.3 V/5.0 V input reference voltage

–

ADC and its reference can be supplied with a voltage independent from VDDIO

–

ADC supply can be equal or higher than VDDIO

–

ADC supply and ADC reference are not independent from each other (both

internally bonded to same pad)

–

Sample times of 2 (default), 8, 64 or 128 ADC clock cycles
