This pin has multiple functions.

 

 

 

 

 

 

• For SH-3 mode, this pin inputs the write enable signal for the

 

 

 

 

 

 

lower data byte (WE0#).

• For MC68K Bus 1, this pin must be tied to IO VDD.

• For MC68K Bus 2, this pin inputs the bus size bit 0 (SIZ0).

 

 

 

 

 

 

 

 

 

 

 

 

• For Generic Bus, this pin inputs the write enable signal for the

 

 

 

 

 

 

lower data byte (WE0#).

 

 

 

 

 

 

See Table 5-9: “Host Bus Interface Pin Mapping,” on page 32.

 

 

 

 

 

 

 

 

 

 

 

 

 

The active polarity of the WAIT# output is configurable on the

 

 

 

 

 

 

rising edge of RESET# - see Section 5.5, “Summary of

 

 

 

 

 

 

Configuration Options” on page 31.

 

 

 

 

 

 

This pin has multiple functions.

 

 

 

 

 

 

• For SH-3 mode, this pin outputs the wait request signal

 

 

 

 

 

 

(WAIT#); MD5 must be pulled low during reset by the internal

 

 

 

 

 

 

pull-down resistor.

• For MC68K Bus 1, this pin outputs the data transfer

acknowledge signal (DTACK#); MD5 must be pulled high

 

 

 

 

 

 

during reset by an external pull-up resistor.

 

 

 

 

 

 

• For MC68K Bus 2, this pin outputs the data transfer and size

 

 

 

 

 

 

acknowledge bit 1 (DSACK1#); MD5 must be pulled high

 

 

 

 

 

 

during reset by an external pull-up resistor.

 

 

 

 

 

 

• For Generic Bus, this pin outputs the wait signal (WAIT#); MD5
