See Table 4-8: “Host Bus Interface Pin Mapping,” on page 29 for summary. WE0# I 10 LIS HIOVDD 1 This input pin has multiple functions. • For Generic #1, this pin inputs the write enable signal for the lower data byte (WE0#). • For Generic #2, this pin inputs the write enable signal (WE#) • For SH-3/SH-4, this pin inputs the write enable signal for data byte 0 (WE0#). • For MC68K #1, this pin must be tied to HIO VDD • For MC68K #2, this pin inputs the bus size bit 0 (SIZ0). • For REDCAP2, this pin inputs the byte enable signal for the D[7:0] data byte (EB1). • For DragonBall, this pin inputs the byte enable signal for the D[7:0] data byte (LWE). See Table 4-8: “Host Bus Interface Pin Mapping,” on page 29 for summary. WE1# I 11 LIS HIOVDD 1 This input pin has multiple functions. • For Generic #1, this pin inputs the write enable signal for the upper data byte (WE1#). • For Generic #2, this pin inputs the byte enable signal for the high data byte (BHE#). • For SH-3/SH-4, this pin inputs the write enable signal for data byte 1 (WE1#). • For MC68K #1, this pin inputs the upper data strobe (UDS#). • For MC68K #2, this pin inputs the data strobe (DS#). • For REDCAP2, this pin inputs the byte enable signal for the D[15:8] data byte (EB0). • For DragonBall, this pin inputs the byte enable signal for the D[15:8] data byte (UWE). See Table 4-8: “Host Bus Interface Pin Mapping,” on page 29 for summary. CS# I 6 LI HIOVDD 1 Chip select input. See Table 4-8: “Host Bus Interface Pin Mapping,” on page 29 for summary. M/R# I 7 LIS HIOVDD 0 This input pin is used to select between the display buffer and register address spaces of the S1D13706. M/R# is set high to access the display buffer and low to access the registers. See Table 4-8: “Host Bus Interface Pin Mapping,” on page 29 for summary.
