D.2
Reset in T1 State: Figure D.1 is a timing diagram for the case in which RES goes low during the
T1 state of an external memory access cycle. As soon as RES goes low, all ports are initialized to
the input state. AS, RD, HWR, and LWR go high, and the data bus goes to the high-impedance
state. The address bus is initialized to the low output level 0.5 state after the low level of RES is
sampled. Sampling of RES takes place at the fall of the system clock ( ).
