How to use JavaScript tiny assembler for NAND6 computer: Write the assembler code in the left textarea. Hexadecimal code will be made in the right textarea. Always use hexadecimal, 2 digits for 1 byte value, and 3 digits for address. Either "Ox" or "h" is NOT needed. ORG statement can be used to specify absolute address. Label can contain alphabet, number and underscore. It must be end with ":". Case-non specific. Comment can be inserted by using either "#", ";", "//", or "/* */". Syntax: NOP : No operation. Store 0x3F in R0. NAND Rx,Ry,Rz : Store NAND value of Rx and Ry in Rz. NAND Rx,Ry,(zz) : Store NAND value of Rx and Ry in memory (zz). NAND Rx,(yy),Rz : Store NAND value of Rx and memory (yy) in Rz. NAND Rx,yy,Rz : Store NAND value of Rx and 6 bit value yy in Rz. JUMP label: : Jump to address shown by label:. SL Rx : Shift left Rx. SJIC Rx,label: : Shift left Rx. Jump to address shown by label: if carry. LD Rx,yy : Store 6 bit value yy in Rx. CALL label: : Store return address in R2 and R3, then jump. RET : Jump to 1C2. Emulation Emulator Program counter : # of steps to run : Break at : 000: 00 00 R0:00 R1:00 R2:00 R3:00 R4:00 R5:00 R6:00 R7:00
