Post by thread:translating 68hc code to pic16f84

Alice, if that's a 68HC11, get the Motorola "M68HC11 Reference Manual".

Are you trying to translate form PIC to 68hc00? There are HUGE differences.

What I meant was 68xx, it is an entire family based on the same code masking and register structure. At 09:38 AM 1/12/2000 -0500, you wrote: {Quote hidden}>"Terry A.

And, there did used to be a MC6800, MC68C00, and even a 68B00 At 09:38 AM 1/12/2000 -0500, you wrote: {Quote hidden}>"Terry A. Steen" wrote: > >> Are you trying to translate form PIC to 68hc00?

Sorry for being vague, now i realize there are big differences among members of the family. The processor used was a 68HC705J1a. I am trying to port the code From this To pic 16F84. The mnemonics i can guess are lda--load something cmp--compare something jmp--some sort of goto bset--bit set more or less bsf bclr---clear bit brclr--branch if clear sub--subtract inc--increment the ones i cant guess are txa jsr rts--rats? beq sta--??static variable??more or less an equate? bhs nega--negate? blo---branch low?? bpl--some sort of conditional branch? bne--branch not equal? ldx adc sbc I probably missed a few but you see the idea. All i Ihink i need (she said, not knowing any better) are the translations of the mnemonics, the code isnt all that complex as far as i can see. thanks alice

Hi Alice, The Motorola doc that you need is: MC68HC705J1A/D Motorola provides their docs free, and they may be ordered at: http://www.mot-sps.com/home/lit_ord.html Here are a couple of other Motorola doc links: http://mot-sps.com/books/current.html http://www.mot-sps.com/lit/ldc_inv.html Hope that this helps, - Nick - Alice Campbell wrote: {Quote hidden}> > Date sent: Wed, 12 Jan 2000 04:36:51 -0800 > Send reply to: pic microcontroller discussion list <EraseMEPICLISTMITVMA.MIT.EDU> > From: <RemoveME1502amcEraseMEEraseMELO.SCSENG.COM> > Subject: Re: translating 68hc code to pic16f84 > To: RemoveMEPICLISTspam_OUTKILLspamMITVMA.MIT.EDU > > Ok.

> 68HC705J1a. I am trying to port the code From this To pic 16F84. Of the "6805" clan.

1. Somewhere I have an even older 6800 / 6802 program listing for speech recognition. Could probably find it. 2. the ones i cant guess are txa jsr kump subroutine rts return from subroutine beq branch if result of last test was zero (zero flag set) sta- store a accumultor to ... bhs possibly - branch if half carry flag set (used for eg bcd arithmetic) nega- -negate? Yes blo---branch low?? - probably bpl-- some sort of conditional branch? bne--branch not equal? YES ldx load index register with ... adc add with carry bit sbc subtract with carry bit I probably missed a few but you see the idea. All i Ihink i need (she said, not knowing any better) are the translations of the mnemonics, the code isnt all that complex as far as i can see. thanks alice
