CCCC 1101011 CZ L DDDDDDDDD 000101001 SETCZ D/# {WC,WZ}
Sets the C & Z flags according to D[1:0] and WC, WZ
If WC is specified then C=D[1] (0=C cleared, 1=C set)
If WZ is specified then Z=D[0] (0=Z cleared, 1=Z set) (yes, 1 sets Zero flag)
If neither WC nor WZ is specified, then C & Z flags are not set/changed
If both WC and WZ are specified, then both C & Z flags are set/changed
I have verified the above with v10a.
Note to Chip
Might it be possible/easy to have SETCZ when neither WC nor WZ is specified, that D[1:0] is set/written with the contents of C & Z flags (ie the reverse of SETCZ D WC,WZ) ? It could be called SAVECZ.
FYI This can be achieved by using 2 SETBx instructions.
setbc x,#1 setbz x,#0Enjoy!

Here's some of my notes on these instructions to refresh our memory on them.
The PUSHZC/POPZC instructions rotate ZC states thru the source address as follows. PUSHZC rotates left x 2 thru source address. Z/C flags are only updated if WZ/WC effects are nominated. +-----------> Z flag ----+ | | | +-------> C flag ------+ | | | | WZ WC | | | | ^ ^ | | | | V V 31 30.................... 1 0 <----------------------- rotated left x2 POPZC rotates right x 2 thru source address Z/C flags are only updated if WZ/WC effects are nominated. +------------ Z flag <---+ | | | +-------- C flag <-----+ | | | | | | WZ WC | | ^ ^ | | | | V V | | 31 30.................... 1 0 -----------------------> rotated right x2These enabled saving and restoring zc flags.A 16 level flag stack basically.
It seems to have only partial opcode construction details
eg with fasmg, https://flatassembler.net/download.php
and using a Chip docs example, I find/guess this is the required form of WAITX
- looks ok for the 32b case ?

Your macro will also have to deal with non immediate variants too.
WAITX myregI can see only a L bit in WAITX, which I assumed was Long immediate, or does that mean L=0 is RegAdr, and all immediates are 32b prefixed ? ( L == #32)
In that case, the macro gives this
