OUTA P5;
OUTA P4; set clkout pin in high state
LDIA #0100B;
OUTA P16; Sleep
:
To enable a CLKOUT signal with frequency

:
RESETTING FUNCTION
When CPU in normal working condition and RESET pin holds in low level for three instruction cycles
at least, then CPU begins to initialize the whole internal states, and when RESET pin changes to high
level, CPU begins to work in normal condition.
The CPU internal state during reset condition is as following table :
Hardware condition in RESET state
