Turns ON when an error occurs in processing an instructions, indi-
cating an error end to the instruction.
Turns ON when an attempt is made to access an illegal area. The
status of this flag is maintain only during the current cycle and only
in the task in which it occurred.
Turns ON when there is a carry or borrow in a math operation,
when a bit is shifted into the Carry Flag, etc.
Turns ON when the result of comparing two values is “greater
than,” when a value exceeds a specified range, etc.
Turns ON when the result of comparing two values is “equals,”
when the result of a math operation is 0, etc.
Turns ON when the result of comparing two values is “less than,”
when a value is below a specified range, etc.
Turns ON when the MSB in the result of a math operation is 1.
Turns ON when the result of a math operation overflows.
Turns ON when the result of a math operation underflows.
Turns ON when the result of comparing two values is “greater than
or equals.”
Turns ON when the result of comparing two values is “not equal.”
Turns ON when the result of comparing two values is “less than or
equals.”
This flag is always ON.
This flag is always OFF.
