    摘要: A microcomputer system having a central processor, a plurality of memory types and a bus interface circuit is configured to allow an external device to download and upload data to/from the various memories using a download circuit connected to the plurality of memories via the bus interface circuit. In operation, a first reset signal, a second reset signal and a mode set signal operate to control whether the central processor or the download circuit will be active, and whether a selector will couple the central processing unit or the download circuit to the bus interface circuit.

    摘要: A microcomputer for checking a flag in a flag circuit to determine whether or not to decrement a count of a program counter. If the flag indicates execution of a STOP instruction, the program counter value is decremented so that the address of a destination to return to at the end of debug interrupt handling is replaced by the address of the STOP instruction. If the flag gives any other indication, the program counter value is used unchanged as the return destination address that will be in effect at the end of debug interrupt handling.

    摘要: In a level conversion circuit, two P channel MOS transistors form a current mirror circuit. When an input signal rises from the “L” level to the “H” level, an N channel MOS transistor connected to a drain of one P channel MOS transistor is brought out of conduction to prevent a leak current from flowing through two P channel MOS transistors, which decreases a power consumption. In addition, when the input signal rises from the “L” level to the “H” level, a P channel MOS transistor connected to a drain of the other P channel MOS transistor is brought into conduction to fix a potential of a node of the drain of the other P channel MOS transistor to the “H” level, which prevents the potential of the node from becoming unstable.

    摘要: When a first signal is switched from an L level to an H level and a second signal is switched from an H level to an L level, and a first constant current source cannot follow the switching immediately thereafter and has not yet been switched, a first node remains at an H level, so an output node remains at an L level. In such state, a second node having been connected to a third node of an H level before the switching becomes connected to the first node of an H level by the switching. At the same time, the output part of an inverter is switched from an H level to an L level, causing the second node to be switched from an H level to an L level as well via a capacitor. At this time, the potential of the first node is reduced to become equal to the second node, to make a transition to an L level.
