According to 604eUM_book (see 8.3.3 Reset inputs p8-54), the IP bit is set for hreset and the vector is at offset 0x100 from the exception prefix.

No difference in this area between 604 and 604e.

This breaks system_reset. Maybe the excp_prefix should be reset to
original value on reset?

Is system_reset supposed to be a soft reset or an hard reset ?

Maybe the firmware you used doesn't handle soft reset.
