LOW Pin
Function
Make the specified pin output low.
• Pin is a variable/constant/expression (0 – 15) that specifies which
I/O pin to set low. This pin will be placed into output mode.
Explanation
The LOW command sets the specified pin to 0 (a 0 volt level) and then sets
its mode to output. For example,
LOW 6
does exactly the same thing as:
OUT6 = 0
DIR6 = 1
Using the LOW command is faster, in this case.
