Abstract
A microcomputer with a built-in non-volatile semiconductor memory, which can automatically perform a work of temporarily interrupting automatic writing or automatic erase and accepting an interruption process when an interruption occurs during the automatic writing or automatic erase by using an interrupt request signal for a microcomputer as an external input for controlling automatic writing or automatic erase of a flash memory.
Claims8
A microcomputer comprising:
- at least a CPU capable of executing an automatic erase sequence and an automatic write sequence, provided in said microcomputer;
- a non-volatile memory whose automatic erase and automatic writing can be interrupted and resumed under external control;
- and
- a peripheral device,
- whereby said automatic erase or automatic writing of said non-volatile memory is temporarily interrupted in response to an interruption request from said peripheral device or outside, so that said CPU can read data from said non-volatile memory.
