The emulator uses a devices internal high-speed clock oscillator (hereafter the HOCO) to achieve communications with the device. Therefore, the HOCO is always in an oscillating state no matter how the HOCO-related registers are set. |
If there is a contention between switching of the HOCO frequency and memory access, the memory access operation is not guaranteed. |
If the debugger has been started up in user boot mode, do not control the high-speed on-chip oscillator power supply control register (HOCOPCR) to turn the power supply of the HOCO off. Otherwise the emulator will not be able to control the microcontroller. |
