Power up reset

[ShawnB]

Acetronics,

I made the changes you recommended and that appears to have corrected the problem.

I do have a questions regarding how the MCLR and BOR fuction work. If either or both are enabled, what happens on power-on? In the data sheets it appears to me that it sets all the ports to 0. Where on a power-on leaves the ports unchanged. Does one have priority over the others or are there all reseting at the same time?

Thanks,
Shawn

Hi, Shawn

MCLR is the " Manual reset " pin

BOR is the " Voltage Supply weakness " reset ... to avoid unwanted behaviour.


Now ...

MCLR has "absolute priority" over everything ...


Remember all ports are left inputs @ Power-Up and nothing is sure until you write what you want to get ...
