initiates a read-modify-write cycle with a MEM_START pulse. 150 ns later MEM_BEGIN sets at the beginning of READ. 150 ns or more later STROBE is sent when the CPU should grab the READ data. 50 ns after TP2, INHIBIT begins. 100 ns after TP2, WRITE is asserted. 400 ns after WRITE begins, WRITE ends and MEM_DONE is sent to the CPU. 350 ns later, READ ends. 0 150 300 650 TP2 50 100 500 MEMSTART(0)
