WE1# I 9 11 CS Hi-Z This pin has multiple functions.
• For SH-3 mode, this pin inputs the write enable signal for the
upper data byte (WE1#).
• For MC68K Bus 1, this pin inputs the upper data strobe
(UDS#).
• For MC68K Bus 2, this pin inputs the data strobe (DS#).
• For Generic Bus, this pin inputs the write enable signal for the
upper data byte (WE1#).

M/R# I 5 7 C Hi-Z This input pin is used to select between the memory and register
address spaces of the S1D13504. M/R# is set high to access the
memory and low to access the registers. See Section 8.1, “Regis-
ter Mapping” on page 64.
