I use xds100 simulator to simulate c6745. After power on, in the function device_init, The program "while ((psc0 - > ptstat) & 0x00000001)" runs all the time. The reason for finding is that gostat [0] in psc0 register is always 1. But my circuit board has just been powered on. What does it mean that gostat [0] is always 1? Is there a problem with my circuit board power supply?
