All the CMOS variants have it, regardless of manufacturer. The manufacturer-specific instructions are:
- RMB/SMB/BBR/BBS - Rockwell/later WDC only
- WAI/STP - later WDC only
- wkjagt 3y agoAren’t WAI and STP only on the 16 bit versions? EDIT: just looked it up, and you’re right! The 65C02S has them. I thought I saw in the WDC programming manual that it was on the 16 bit version. I’m going to play around with those a bit :-)
- zaxomi 3y agoDon't they also have BRA - BRanch Always, PHX PHY PLX PLY - PusH or PulL X or Y register, STZ - STore Zero, TRB - Test and Reset Bits, TSB - Test and Set Bits?
- tom_ 3y agoYes, but those are common to all versions, not manufacturer-specific.
