AB[16:13] I 115-118
CHi-Z
• For Philips PR31500/31700 Bus, these pins are connected to V
DD
.
• For Toshiba TX3912 Bus, these pins are connected to V
DD
.
• For PowerPC Bus, these pins input the system address bits 15
through 18 (A[15:18]).
• For all other busses, these pins input the system address bits 16
through 13 (A[16:13]).
See
“Host Bus Interface Pin Mapping”
for summary. See the respective
AC Timing diagram for detailed functionality.
AB17 I 114
CHi-Z
• For Philips PR31500/31700 Bus, this pin inputs the IO write
command (/CARDIOWR).
• For Toshiba TX3912 Bus, this pin inputs the IO write command
(CARDIOWR*).
• For PowerPC Bus, this pin inputs the system address bit 14 (A14).
• For all other busses, this pin inputs the system address bit 17 (A17).
See
“Host Bus Interface Pin Mapping”
for summary. See the respective
AC Timing diagram for detailed functionality.
AB18 I 113
CHi-Z
• For Philips PR31500/31700 Bus, this pin inputs the IO read
command (/CARDIORD).
• For Toshiba TX3912 Bus, this pin inputs the IO read command
(CARDIORD*).
• For PowerPC Bus, this pin inputs the system address bit 13 (A13).
• For all other busses, this pin inputs the system address bit 18 (A18).
See
“Host Bus Interface Pin Mapping”
for summary. See the respective
AC Timing diagram for detailed functionality.
AB19 I 112
CHi-Z
