Method of controlling data writing into on-board microcomputer |
摘要 |
A user board has an on-board microcomputer including a flash memory and an on-board writing program memory, a user circuit, a reset circuit, a first OR gate, and a second OR gate. A detected signal for resetting the user circuit in an on-board writing mode is supplied from an on-board writing host through the second OR gate to prevent the user circuit from affecting a writing control signal and data to be written into the flash memory.
