Description
This pin has multiple functions.
CS
Input
• For SH-3/SH-4 mode, this pin inputs the read signal
(RD#).
• For MC68K #1, this pin must be tied to IO VDD.
• For MC68K #2, this pin inputs the bus size bit 1 (SIZ1).
• For Generic #1, this pin inputs the read command for the
lower data byte (RD0#).
• For Generic #2, this pin inputs the read command (RD#).
See “Host Bus Interface Pin Mapping” for summary.

High
Impedance
• 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 Generic #1, this pin outputs the wait signal (WAIT#).
• For Generic #2, this pin outputs the wait signal (WAIT#).
