Standard Memory Read Cycle
Page-Mode Read
LAD (TMS34020)
LAD (Memory)
*See clock stretch, page 21.
NOTES: A. LAD (TMS34020): Output to the LAD bus by the TMS34020.
LAD (memory): Output to the LAD bus by the memory.
B. LRDY, PGMD, SIZE16, and BUSFLT are not sampled on subsequent page-mode cycle accesses to 32-bit-wide memory space.
Figure 2. Local Memory Read Cycle Timing (With Page Mode)
During the address output to the LAD bus by the TMS34020, the least significant four bits (LAD0–LAD2) contain
a bus status code. PGMD low at the start of Q2 after RAS low indicates that this memory supports page-mode
operation. LRDY high at the start of Q2 after RAS low indicates that the cycle can continue without inserting wait
states. DDOUT returns high after the initial address output on LAD (during Q4), indicating that a memory read
cycle is about to take place.
