SP60
Value less than
on when the accumulator value is less than the instruction value.
SP61
Value equal to
on when the accumulator value is equal to the instruction value.
SP62
Greater than
on when the accumulator value is greater than the instruction value.
SP63
Zero
on when the result of the instruction is zero (in the accumulator.)
SP64
Half borrow
on when the 16 bit subtraction instruction results in a borrow.
SP65
Borrow
on when the 32 bit subtraction instruction results in a borrow.
