#123631 - /R & /W OR /IOR & /IOW |
Hello every body.
I am doing an application(UART based - SERIAL comm.) based on microcontroller. In that application the DEVICE(IC ST16C554) need /IOR and /IOW lines. But as we all know that a microcontroller has only /R and /W lines. Now what shall I do? ----Can I connect /R and /W lines of microcontroller to the other DEVICE(IC ST16C554), insted of /IOR and /IOW lines. that is as shown below-- ----------------- -------------------------- microcontroller | | ST16C554 UART side | | side /R |------------------|/IOR /W |------------------|/IOW | | ------------------- --------------------------- One more doubt ;;;;;;;; When to use level triggred and when to use edge triggred interrupts. Pls explain with diagram. |
