Thanks

Since my source supports several devices, based on some #define symbols, I decide to use the commandline option batch file.

According to the help file, I construct one like this

c:\progra~1\picc ...

Thanks, I will follow your suggestions

BTW, I am using PIC18F8620 with CCSC 3.212

and I initialize MMCPOWERE =0

I define
#bit GRNLED_SEL = PORTF.2
#bit MMCPOWERE = TRISF.3
#bit MMCPOWER = LATF.3

When I assign GRNLED_SEL=1, it affects the state of MMCPOWER.

Thanks for your time

As I stated in my last post, I finally realized my test condition was not really a brown-out case, but a slow discharging, thus I will not see ...

Thanks, I will confirm that.

According to the 18F8620 user manual (section 3.5) and my setup, brownout reset should occur when supply is below 4.2V for more than 200us, and the chip will remain in ...

I just tried CCS 2.212, and the fuses were set correctly.

Now, a new question:

When I gradually lower the power supply voltage from 5 all the way down, until the PIC quits, I don't see the Brown ...

Thanks for your quick reply.

I tried BROWNOUT, and it simply doesn't work at all with CCS 3.186, but BORV42 works fine.

I will try some later version of CCS to see if it works there

I am using Picc 3.186

BTW:

How do I specify 4.2V brownout voltage?

How do I detect a brownout from the software? (Checking RCON register?)

I am using 18F8620 in my design, and my application requires Brownout detect with Brown out voltage at 4.2V.

1) When I use #fuses to set up BROWNOUT as:

#include <18F8620.h>
#fuses HS,NOW ...
