TNT4882
Single-Chip IEEE 488.2 Talker/Listener ASIC
ISA Pin Configuration Byte Lane Table
This table shows which byte lane accesses the TNT4882 internal
registers during an I/O access when you use the ISA pin
configuration. All combinations of ADDR4-1, SENSE_8_16N,
and BHEN_N not shown in this table are illegal. You should not
apply these combinations to the TNT4882 while the chip is
selected. The accessed register is determined only by ADDR4-0,
not SENSE_8_16N or BHEN_N.
