D.1.2 Reset Circuit
HALT and RESET are both open-drain signals. When both signals are externally asserted,
the entire MC68302 is reset. HALT is asserted by the MC68302 when the HALT instruction
is executed, and RESET is asserted when the RESET instruction is executed.
The reset circuit shown uses an MC1455 timer to generate a 0.5-sec pulse until DlS reaches
the 2/3 V
below 2/3 V

, then the output pin (O) is pulled low, ending the reset to the MC68302. This
