NOTE: This is written for the BS2
but can be used for the BS2e,
BS2sx and BS2p also. Locate the
proper source code file or modify
the STAMP directive before
downloading to the BS2e, BS2sx or
BS2p.

STOP
sx p
Function
Stop program execution.
Explanation
STOP prevents the BASIC Stamp from executing any further instructions
until it is reset. The following actions will reset the BASIC Stamp:
1. Pressing and releasing the RESET button on the development
board.
2. Driving the RES pin low then letting it float (high).
3. Downloading a new program
4. Disconnecting then reconnecting the power.
STOP differs from END in two respects:
1. Stop does not put the BASIC Stamp into low-power mode. The
BASIC Stamp draws just as much current as if it were actively
running program instructions.
2. The output glitch that occurs after a program has "ended" does not
occur after a program has "stopped."
