Signal Description
5.10 MC68302 BUS INTERFACE SIGNAL SUMMARY
Table 5-2 and Table 5-3 summarize all bus signals discussed in the previous paragraphs.
They show the direction of each pin for the following bus masters: M68000 core, IDMA,
SDMA (includes DRAM refresh), and external. Each bus master can access either internal
dual-port RAM and registers or an external device or memory. When an external bus master
accesses the internal dual-port RAM or registers, the access may be synchronous or asyn-
chronous.
When the M68000 core is disabled, BR and BG change their direction, and BCLR becomes
bidirectional.

tomatic vectoring only. AVEC instead of DTACK should be asserted during autovectoring
and should be high otherwise.
When the M68000 core is disabled, this pin operates as IOUT0. IOUT2–IOUT0 provide
the interrupt request output signals from the IMP interrupt controller to an external CPU
when the M68000 core is disabled.
chip-select logic detects address conflict or write protect violation. BERR may be asserted by external logic in all
cases.
BERR is an open-drain output, and may be asserted by the IMP when the hardware watchdog is used or when the
