These are r0 - r3, or R0 - R3 for registers, and plus, PLUS, minus, MINUS, zero, ZERO, gt, GT, lt, LT, eq, EQ, un, UN, always, and ALWAYS for conditions. .H 3 "Destination Register for Indexed Addressing" If the destination register, the one adjacent to the opcode, is not R0 when one of the absolute indexed addressing modes is used, an error is issued. .H 3 "Selection Criteria Keywords" .VL 10 5 .LI "REG0 REG1 REG2 REG3" .SP Some instructions are restricted to a subset of the registers. Only those instructions with the specified registers are valid. .LI "COND0 COND1 COND2 COND3" .SP Some instructions are restricted to a subset of the conditions. Only those instructions with the specified conditions are valid. .VL 10 0 1 .LI "COND0" EQ, or ZERO .LI "COND1 GT, or PLUS .LI "COND2" LT, or MINUS .LI "COND3" ALWAYS, or UN .LE .LE .H 3 "Apostrophes" The apostrophes in the syntax field are a notation used for the parser generator and are not put in the assembler source statement. .H 2 "Notes" .H 3 "Location Counter" The Dollar Sign is used as the location counter symbol in this assembler. .H 3 "Memory Addressing Error Messages" .VL 5 0 .LI "ERROR - expression exceeds available field width" .SP This message occurs when : .DL .LI The absolute branch address is to an invalid address, one greater than 32767. .LI The absolute or relative address was not in the present memory page. .LI The relative offset was outside the range that can be represented in 7 bits. .LE .LI "ERROR - instruction crosses page boundary" .SP The first and last bytes of an instruction are on different sides of an 8k page. .LI "WARNING - Page Boundary" .SP The first byte of an instruction is on a 8k page boundry. .H 3 "Page Wraparound for Relative Addressing" The wraparound of an effective address, where a relative address from an instruction near a page boundary accesses memory at the other side of the page, is not supported in this assembler and will result in one or more error messages. .P This does not apply to the ZBRR and ZBSR instructions. Memory destinations for these can range from 0 to $3f and $1fc0 to $1fff. .H 3 "Relational Operators" The relational operator keywords GT, LT, and EQ are not available. The '<', '>', and '==' special character representations must be used. .H 3 "Reserved Symbols" .H 4 "Machine Dependent Reserved Symbols" ALWAYS AND DEFINED EQ GE GT HIGH LE LOW LT MINUS MOD NE NOT OR PLUS R0 R1 R2 R3 SHL SHR UN XOR ZERO always and defined eq ge gt high le low lt minus mod ne not or plus r0 r1 r2 r3 shl shr un xor zero .TC 1 1 7
