Does reset exception processing start after the bus cycle has ended?

Latest Updated:03/25/2009

Question:

When a reset is input during accessing to the external memory (during a bus cycle), does reset exception processing start after the bus cycle has ended?

Answer:

- Power-on reset
The LSI becomes to be a power-on reset state on receipt of the reset regardless of the completion of a bus cycle, and reset exception processing starts.

- Manual reset
The Bus State Controller continues to operate even in the manual reset status.
When the LSI enters manual reset status in the middle of a bus cycle, manual reset exception processing does not start until the bus cycle has ended.
