WAIT# O 17 LB2A HIOVDD Hi-Z
During a data transfer, this output pin is driven active to force the
system to insert wait states. It is driven inactive to indicate the
completion of a data transfer. WAIT# is released to the high
impedance state after the data transfer is complete. Its active
polarity is configurable. See Table 4-8: “Summary of Power-
On/Reset Options,” on page 29.
• For Generic #1, this pin outputs the wait signal (WAIT#).
• For Generic #2, this pin outputs the wait signal (WAIT#).
• For SH-3 mode, this pin outputs the wait request signal
(WAIT#).
• For SH-4 mode, this pin outputs the device ready signal
(RDY#).
• For MC68K #1, this pin outputs the data transfer acknowledge
signal (DTACK#).
• For MC68K #2, this pin outputs the data transfer and size
acknowledge bit 1 (DSACK1#).
• For REDCAP2, this pin is unused (Hi-Z).
• For DragonBall, this pin outputs the data transfer acknowledge
signal (DTACK
).

RESET# I 13 LIS HIOVDD 0
Active low input to set all internal registers to the default state and
to force all signals to their inactive states.
