The macro commands that are register transfer commands (with the exception of the double
shifts) have the same error checks as a non-macro register transfer command, plus some
additional checks. An error will be flagged when the user attempts to:
Register Transfer MACRO
0,
anything
Register Transfer MACRO anything,
Z
Register Transfer MACRO anything,
T
The from-to bits in the instruction will not be deleted on any of the above errors. The error
tag only signifies that the instruction should be examined to see if it is correct.
The macro commands SMA, SMB, SAM and SBM, will have the same error checks and same
addressing capabilities as non-macro commands requiring a memory address.
No error checks are perfomed on the macro double shift commands SLD and SRD. The operand
must be decimal and must be left- justified in the operand field.
