16-Bit, 2-State Access Space: Figures 4.11 to 4.13 show bus timings for a 16-bit, 2-state access

space. When a 16-bit access space is accessed, the upper half (D15 to D8) of the data bus is used

for odd addresses, and the lower half (D7 to D0) for even addresses.

Wait states cannot be inserted.

Notes: 1. n = 0 to 7

2. When RDNn = 0
