Description
Indicates access to the DDR-SDRAM space
Indicates access to an internal register of this
LSI
Indicates an address phase
Indicates an access cycle period
Indicates whether it is data write or read
Indicates the access size
Note: These pins are used in the SH7750
During an address phase, signals on EX_AD25
to EX_AD0 are input as an address
During a data phase, signals on EX_AD25 to
EX_AD0 are input as data
Wait state request signal
Interrupt signal
0: External CPU is not connected
1: External CPU is connected
Group. In the SH7751 Group, pins D31 to
D29 act as access size signals.
