Appendix D Pin States
Reset in T3 State: Figure D.3 is a timing diagram for the case in which RES goes low during the
T3 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 outputs are held during the T3 state.The same timing applies when a reset
occurs in the T2 state of an access cycle to a two-state-access area.
