RM57L843: Hardware connection with Dual Port RAM(70V261)

Part Number: RM57L843

Dear.

DPRAM(70V261) has Left/Right Interrupt port and Left/Right Semaphore ports.

I guess those pins should be connected to RM57 ports related to EMIF. 

Please give me a guide where I should connect those DPRAM's interrupt and Semaphore ports to RM57. 

Thanks alot

  • Hello Inseok,

    The EMIF doesn't have pins for 70V261's interrupt flag and semaphore enable signals. I just read 70V261 datasheet, RM57 GIO pins can be used to monitor 70V261's interrupt flag and output an low level signal to enable the semaphore.
