Abstract
A microcontroller of the present invention includes: input/output ports; peripheral functional blocks, associated with the input/output ports, for performing predetermined functions; a clock signal generating circuit; a function selection decoder circuit for decoding a mode signal input from function selection pins and outputting a function selection signal; a clock signal controlling section for controlling supply/stop of a clock signal to each of the functional blocks in response to the function selection signal; and a port controlling block for setting functions of the input/output ports in response to the function selection signal.
Claims10
A microcontroller comprising:
- input/output ports;
- functional blocks, each associated with one of the input/output ports, for performing predetermined functions;
- a clock signal generating section, which generates a clock signal supplied to each of the functional blocks;
- and
- a clock signal controlling section, which controls supply/stop of the clock signal to the functional blocks in response to an externally-supplied mode signal.

- a clock signal controlling section, which controls supply/stop of the clock signal to the functional blocks in response to an externally-supplied mode signal;
- and
- a responding section, which outputs a response signal in place of the functional blocks, when the functional blocks are accessed while the clock signal is not supplied thereto, the signal indicating that the access is erroneous.
