Reset
There are three ways in which a reset can occur.
Power on reset
A low pulse onto RES pin
time-out
After these reset conditions, the Program Counter and
Stack Pointer will be cleared to 0.
To guarantee that the system oscillator is started and
stabilized, the System Start-up Timer or SST provides
an extra-delay of 1024 system clock pulses when the
system is reset or awakes from the Sleep or Idle opera-
tion mode.
By examining the processor status flags PD and TO, the
software program can distinguish between the different
chip resets .
