CPUy setting CPUx into Idle - AURIX TC29X

I would like to ask if someone has experience in using Infineon's IfxCpu_setCoreMode API function (In IfxCpu.c) to place a CPU into Idle mode by another CPU?

Calling IfxCpu_setCoreMode(&MODULE_CPU0, IfxCpu_CoreMode_idle); from CPU1 causes CPU0 to reset instead of placing it in Idle.

Any help would be much appreciated.
