C which corrected all the above mentioned bugs. The buglist for the NS32GX32 was published in the december '89 issue of uP Report. The only addition for the NS32532 buglist is that RDVAL and WRVAL instructions can produce a wrong result if address bit A31 is high and the protection level is not OK. Bottom line: There is absolutely no problems for '532 developers out there: The S/W tools are available, the HP ISE is available, support is available, and naturally, CLEAN AND SOLID SILICON IS AVAILABLE !!
