Normally, such synchronous actions can be performed by coding a program on the CPU side. However, this function is useful
when no delay caused by CPU interrupt handling or program execution time is allowed. The synchronous action of this IC is a
function that executes a specified action immediately when a specified activation factor occurs. This linked action is performed
without CPU intervention, achieving high-precision synchronous control.
One synchronous action set means that performs a specified action when a specified activation factor occurs. MCX514 has
independent 4 synchronous action sets in each axis.
It can perform 4 synchronous action sets independently, in addition can perform them in cooperation among axes.
Each synchronous action set SYNC0
～
3 has 15 types of activation factors in each axis, the user selects one and configures it by
the code. And about actions that are activated, 24 types of actions are provided.
