Hi, I have the following queries to be clarified a) Does eTPU in MPC5777C has ROM memory that contains microcode with preprogrammed functions like similar to MC68332 Microcontroller which has TPU with ROM memory that contains factory preprogrammed functions with Mask Set G. b) Does any microcontroller in MPC57xx family has eTPU with ROM memory that contains microcode with preprogrammed functions? c) As understood by us from reference manual of MPC5777C, the eTPU includes 36KB code RAM and 9 KB parameter RAM only due to which the microcode has to be loaded into code RAM of eTPU everytime when we power on the MCU. This loading of microcode into code RAM of eTPU will affect the bootup time of our application so can you suggest any other solution to avoid loading of microcode into code RAM of eTPU everytime when we power on the MCU.
