RESET#
State
The active polarity of the WAIT# output is configurable; the state of MD5
on the rising edge of RESET# defines the active polarity of WAIT# - see
“Summary of Configuration Options” .
• For SH-3 Bus, this pin outputs the wait request signal (WAIT#); MD5
• For SH-4 Bus, this pin outputs the ready signal (RDY#); MD5 must
• For MC68K Bus 1, this pin outputs the data transfer acknowledge
• For MC68K Bus 2, this pin outputs the data transfer and size
• For Generic Bus, this pin outputs the wait signal (WAIT#); MD5 must
• For MIPS/ISA Bus, this pin outputs the IO channel ready signal
• For Philips PR31500/31700 Bus, this pin outputs the wait state signal
• For Toshiba TX3912 Bus, this pin outputs the wait state signal
• For PowerPC Bus, this pin outputs the transfer acknowledge signal
• For PC Card (PCMCIA) Bus, this pin outputs the wait signal (-WAIT);
See “Host Bus Interface Pin Mapping” for summary. See the respective
AC Timing diagram for detailed functionality.
Active low input that clears all internal registers and forces all outputs to
their inactive states. Note that active high RESET signals must be
inverted before input to this pin.
