We are migrating from MPC8260 to MPC8270. In the datasheet we see the HID2 register but unable to find the default value of the register. We would like to know what is the status of the 4 additional cache registers in MPC8270. (We have initialized only the first 4 cache lines that is available in MPC8260). Are the 4 additional cache lines enabled by default in MPC8270?
