eTimer module

The SPC56XL70 provides two eTimer modules on the LQFP144 package. Six 16-bit

general purpose up/down timer/counters per module are implemented with the following

features:



Maximum clock frequency of 120 MHz



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

–

Equals peripheral clock divided by 2 for external event counting

–

Equals peripheral clock for internal clock counting



Cascadeable counters



Programmable count modulo



Quadrature decode capabilities



Counters can share available input pins



Count once or repeatedly



Preloadable counters



Pins available as GPIO when timer functionality not in use



DMA support

1.5.32

Sine wave generator (SWG)

A digital-to-analog converter is available to generate a sine wave based on 32 stored values

for external devices (ex: resolver).



Frequency range from 1 KHz to 50 KHz



Sine wave amplitude from 0.47 V to 2.26 V
