Function
If the Condition Code evaluates True, write the parameter-
specified immediate value to the dedicated WMI memory
pointer (a register not accessible by the host). Otherwise
(Condition Code Evaluates False), continue execution at the
next op code in the BC Instruction List.
Immediate value must exceed 0x4F or WMP instruction has
no effect. After reset, the default WMI memory pointer value
is 0x0050.
If the Condition Code evaluates True, write the parameter-
specified immediate value to 0x0050 or the memory
address specified by the last WMP instruction performed.
Otherwise (Condition Code Evaluates False), continue
execution at the next op code in the BC Instruction List.
If the Condition Code evaluates True, the memory address
specified by the parameter word is decremented. If the new
value is non-zero, the next instruction is executed. If the
decremented value is zero, the next instruction is skipped.
Otherwise (Condition Code Evaluates False), continue
execution at the next op code in the BC Instruction List.
The primary purpose of DSZ is N-iteration repeating
execution loops. N is initialized with a WMI op code, and the
instruction following DSZ is a JMP to top-of-loop.
The parameter word value is used to set, clear, or toggle
the lower byte in the BC General Purpose Flag Register
0x0037. The upper and lower bytes in the parameter word
provide 2-bit arguments that modify each of the eight GP
flag bits, as illustrated below.
