The motor control connector
The STR750FV2 is an MCU suited for Motor Control applications since it embeds timers
which can be used for dead time generation and edge/center aligned waveform emergency
stop. This feature makes it ideal for induction and brushless DC motor control.
The STR750-MAP is provided with a 34-pin fully featured connector (J11 in the board
layout) dedicated to these kinds of applications.
Table 3 below lists the association between each connector pin and the related functionality
and microcontroller pin correspondence.
