... CAS controls its corresponding I/O tristate logic (in conjunction with OE and WE and RAS). LCAS controls I/O0 - I/O7 and UCAS controls I/O8 - I/O15. The IS41LV16257B CAS function is determined by the first CAS (LCAS or UCAS) transitioning LOW and the last transitioning back HIGH. The two CAS controls give the IS41LV16257B both BYTE READ and BYTE WRITE cycle capabilities ...
