    There are other such Pseudo-Instructions. I've found that TESTB reg,#bit is the same as ISOB reg,#bit NR

    Hi Chip.


    How I can in PNut write that table.
    tab1_  org  $         '';direct commands 
       Byte "list"                                                        ' Any place in assembly code
       Word list         ''shr 8 + 128,list and 255                                 ' Any place in assembly code
       Byte "run"
       Word run             ''shr 8 + 128,run and 255    '<----------------- Original in 8080 assembly BYTE,BYTE

    Hi Chip.

    Forget it.

    I found my problem --- If I use WORD's it adds 0 to fill LONG's --- That disturbed my scan routine.
    Now That are fix

    Ps to previous post.

    That function for me.
    tab1_  org  $         '';direct commands 
       Byte "list"
       byte $80+list>>8,list         ''shr 8 + 128,list and 255
       Byte "run"
       byte $80+run>>8,run             ''shr 8 + 128,run and 255

    Hi Chip.

    Are $1F6,$1F7 (INDA, INDB] direct addressable else can this position can be used for other usage ?

    And INDA, INDB can only be addressed by SETINDA,SETINDB

    Hi Chip.

    What are difference between this 2 RET instructions

    And Can You give syntax examples on one that are different from Propeller 1
    ''000111 ZC0 1 CCCC 000000000 000000000    |   RET        |           | ''Return from subroutine            4 *
''111010 001 1 1111 000000000 000000000    |   RET        |           | ''Like JMP, but assembler handles details

    My list shows opcode 111010 as CFGPINS & INCMOD.
    There is opcode 111010 which is JMPRETD, a delayed JMPRET.

    Hi Cluso.

    I have.
    I see I need test them by PNut.
    010111 ZCR 0 CCCC DDDDDDDDD SSSSSSSSS        JMPRETD D,S     ''jump to S, store return in D      1

000111 ZCR 0 CCCC DDDDDDDDD SSSSSSSSS        JMPRET  D,S     ''jump to S, store return in D      4 *
000111 ZCR 1 CCCC DDDDDDDDD nnnnnnnnn        JMPRET  D,#n     ''jump to 0..511, store return in D 4 *

111010 000 I CCCC DDDDDDDDD SSSSSSSSS   |   CFGPINS     |   D/#n    | Setup pins masked by register &#8220;D (0-511)&#8221; to register

    Hi Chip.

    Have You any updates on Instructions, counters block diagrams and other things we can have play with ?

    Not yet.

    I'm getting close to having the new Spin interpreter running. This is taking all my work time, for now.

    Chip, by chance, are you including new SPIN constructs to access the four tasks per COG of the Prop II?

    Hi Chip.

    Thanks for reply.

    Good look with SPIN

    Chip,

    I think all of us are looking forward to Spin for Prop2 :-) so it is really nice to hear it is close!

    Yes. The interpreter uses the top half (actually, less) of cog RAM, as well as the top part of the stack RAM, PTRB, INDB, and SPB. This leaves free for PASM code (which could be multitasking): the first half+ of cog RAM, the first part of stack RAM, PTRA, INDA, and SPA.

    Look's as nice solution
