* Instead of having separate flagC, flagZ and flagN variables, I would prefer to have only one: flagsCZN.
* The C and N flags don't conflict; they are always bits 16 and 15 of the last 16-bit arithmetic result (or
* bits 8 and 7 of the last 8-bit arithmetic result). The Z flag is a "bit" more complicated, because it's a
* representation of bits 15-0 (or 7-0), which overlap the N flag bit. That overlap is fine after any given
* arithmetic operation, because of the four possible N and Z combinations:
*
* N Z
* - -
* 0 0 Positive non-zero number
* 0 1 Zero
* 1 0 Negative non-zero number
* 1 1 INVALID
*
* the fourth combination is an impossibility (the world of floating point numbers, with their NaNs, positive
* and negative zeros, infinities, etc, is another story, which doesn't concern us here).
*
* The problem is that some intervening NON-arithmetic instruction (eg, SEN or SEZ) could be executed that sets
* either N or Z independently, resulting in BOTH flags being set.
*
* One way to support that combination would be to define Z as the result of all non-sign bits. However,
* that means that, after any arithmetic operation, we would have to propagate the sign bit of the result to
* one or more other bits in flagsCZN; eg:
*
* flagsCZN = result | ((result & 0x8000) >> 1)
* or:
* flagsCZN = result | ((result & 0xffff)? 1 : 0)
*
* It's worth noting that all that extra work is actually required for only ONE 16-bit value: -32768 or 0x8000
* (and ONE 8-bit value: -128 or 0x80), because all other negative numbers already have 1 or more lower bits set.
*
* A simpler approach would be to leave flagN independent, and only combine flagC and flagZ (into flagCZ).
* Alternatively, we could combine flagC and flagN and leave flagZ independent; the choice is arbitrary. -JP
