The WDT time-out during HALT is different
from other chip reset conditions, since it can
perform a warm reset that resets only the PC
and SP, leaving the other circuits in their origi-
nal state. Some registers remain unchanged
during any other reset conditions. Most regis-
ters are reset to their "initial condition" when
the reset conditions are met. By examining the
PD flag and TO flag, the program can distin-
guish between different "chip resets".

WDT wake-up HALT
Note: "u" stands for "unchange"
To guarantee that the system oscillator has
started and stabilized, the SST (System
Start-up Timer) provides an extra-delay of
1024 system clock pulses after a system power
up or when awakening from a HALT state.
When a system power up occurs, the SST delay
is added during the reset period. But when the
reset comes from the RES pin, the SST delay is
disabled. Any wake-up from HALT will enable
the SST delay.
The functional unit chip reset status is shown
in the table.
