What is the operating frequency of the HT48F I/O TYPE FLASH MCU with EEPROM device series?
Answer In principle when the MCU enters an interrupt routine, the EMI bit will be automatically cleared, which will disable other interrupts from taking place. However in the interrupt routine if the EMI bit is set high and if the Stack still has space, all other interrupts (including identical interrupts) will be executed. To enable identical interrupts, it is important to note that any backed up data must be carefully managed, to prevent it from being corrupted by the new interrupt. Unless it is an interrupt which is of immediate urgency, it is not recommended that interrupts are allowed to take place within other interrupts.
