pic reset?
From: John Pritchard ####@####.#### Date: 22 Feb 2011 15:11:50 -0000 Message-Id: <AANLkTinGW7GomH5bqu-DbvmGS4tYrquuC1ndxCUGTZ1g@mail.gmail.com> Hi, If anyone reading this knows about a RESET opcode, please send pointers. Occasionally in reading MCHP docs I come across an apparent reference to a RESET instruction, but of course when I see it and when I could use it are two different times. Of course the default interpretation is that the apparent reference to a RESET instruction is rather a reference to pulling (down) on (an enabled) MCLR -- or dropping Vdd into a BOR, etc.. And it's easy to imagine that the language of the documentation is not transparent. But I thought I'd ask, anyway.

See any PIC16EMR or PIC18 data sheet. It's simply a clean way for software to initiate a reset. -- Cheers, KHMan (esq.)

Other devices with the 14-bit core and all devices with the 12-bit core lack a reset instruction. The reset instruction nearly the equivalent of the POR reset.

It is theoretically strictly equivalent to a MCLR.

These generally are those that support intosc. to be clear, you check on the reset states of the pic, there will be options for reset (BOR,MCLR etc), which controller are u using? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
