Description
This pin has multiple functions.
• For SH-3/SH-4 mode, this pin inputs system address bit
0 (A0).
• For MC68K #1, this pin inputs the lower data strobe
(LDS#).
• For MC68K #2, this pin inputs system address bit 0 (A0).
• For Generic #1, this pin inputs system address bit 0
(A0).
• For Generic #2, this pin inputs system address bit 0
(A0).
See “Host Bus Interface Pin Mapping” for summary.
Input
These pins input the system address bits 15 through 1
(A[15:1]).
These pins have multiple functions.
• For SH-3/SH-4 mode, these pins are connected to
[D15:0].
• For MC68K #1, these pins are connected to D[15:0].
High
Impedance
• For MC68K #2, these pins are connected to D[31:16] for
a 32-bit device (e.g. MC68030) or D[15:0] for a 16-bit
device (e.g. MC68340).
• For Generic #1, these pins are connected to D[15:0].
• For Generic #2, these pins are connected to D[15:0].
See “Host Bus Interface Pin Mapping” for summary.
