RESET
The processor will perform a reset operation any
time the RESIN pin active. The RESIN pin is actually
synchronized before it is presented internally, which
means that the clock must be operating before a
reset can take effect. From a power-on state, RESIN
must be held active (low) in order to guarantee cor-
rect initialization of the processor.
Failure to pro-
vide RESIN while the device is powering up will
result in unspecified operation of the device.
Figure 14 shows the correct reset sequence when
first applying power to the processor. An external
clock connected to CLKIN must not exceed the V
CC
threshold being applied to the processor. This is nor-
mally not a problem if the clock driver is supplied
with the same V
CC
that supplies the processor.
When attaching a crystal to the device, RESIN must
remain active until both V
CC
and CLKOUT are stable
(the length of time is application specific and de-
pends on the startup characteristics of the crystal
circuit). The RESIN pin is designed to operate cor-
rectly using an RC reset circuit, but the designer
must ensure that the ramp time for V
CC
is not so
long that RESIN is never really sampled at a logic
low level when V
CC
reaches minimum operating
conditions.
Figure 16 shows the timing sequence when RESIN
is applied after V
CC
is stable and the device has
been operating. Note that a reset will terminate all
activity and return the processor to a known operat-
ing state. Any bus operation that is in progress at the
time RESIN is asserted will terminate immediately
(note that most control signals will be driven to their
inactive state first before floating).
While RESIN is active, bus signals LOCK, A19/
ONCE, and A18:16 are configured as inputs and
weakly held high by internal pullup transistors. Only
19/ONCE can be overdriven to a low and is used to
enable ONCE Mode. Forcing LOCK or A18:16 low at
any time while RESIN is low is prohibited and will
cause unspecified device operation.
