SEMA4 In MPC5777

[YangHaha]

Hi, NXP;

I want to know that a SEMA4_GATE is a semaphore implemented by hardware ?

Thus I don't need to define semaphore in software ?

Hello,

The reset state of the IPS_Semaphores module allows it to begin operation without the need for any further initialization. All the internal state machines are cleared by any reset event, allowing the module to immediately begin operation.

You have to control semaphores in SW. Please have a look at application note on how to use them.
