Local bus data out enable. This pin can be used by external
transceivers; it is high when LBD[7:0] are in output mode and low
when they are in input mode.
Local bus active-low Chip-Select (Intel mode)
Local bus active-low Data-Strobe (Motorola mode)
Local bus active-low write-strobe (Intel mode)
Local bus Read-not- Write control (Motorola mode)
Local bus active-low read-strobe (Intel mode)
Permanent high impedance (Motorola mode)
(8-bit mode) Local bus address signals
(32-bit mode) Local bus address signals
(8-bit mode) Local bus data signals
(32-bit mode) Local bus data signals
