This is a multi-purpose pin:
• For SH-3/SH-4 Bus, this pin inputs the read signal (RD#).
• For MC68K Bus 1, this pin is connected to V
• For MC68K Bus 2, this pin inputs the bus size bit 1 (SIZ1).
• For Generic Bus, this pin inputs the read command for the lower data
• For MIPS/ISA Bus, this pin inputs the memory read signal (MEMR#).
• For Philips PR31500/31700 Bus, this pin inputs the memory read
• For Toshiba TX3912 Bus, this pin inputs the memory read command
• For PowerPC Bus, this pin inputs the transfer size 0 signal (TSIZ0).
• For PC Card (PCMCIA) Bus, this pin inputs the output enable signal
See “Host Bus Interface Pin Mapping” for summary. See the respective
AC Timing diagram for detailed functionality.
