Host Interface Pins
Pin Name
Note : The host interface can connect the MB86292 to the SH4 (SH7750) or SH3 (SH7709) from Hitachi Ltd. the
V832 from NEC, or to the SPARClite (MB86833) from Fujitsu without any external circuit in between. (Using
the SRAM interface allows the MB86292 to use another CPU.) The host CPU is set by the MODE0 and
MODE1 pins as shown below.
Note : The MODE2 pin can be used to set the Ready signal level to be used upon completion of the bus cycle. To
use the MODE2 signal at "H" level, set the software setting to two cycles.
