Hi

where in the STM32 documentation would i find out if a stm32 L4 76ZE has a trace buffer?

Get the ARM documentation for the core and check the registers / flags in the ITM and DWT units. 

Don't think it uses a trace buffer. That resides in the trace pod. On the CM0 you can allocate SRAM to the instrumentation code, don't think you do that with CM4.
