The 8 bit CertificateType undicates the certificate type

Cert Types

0: cpuBootloader(zboot), cpuzone
1: cpucode, cpuzone, used to sign cpukernels and applications
2: xtask1, xpuzone, used to develop and release SDK DRM implementations
3: video microcode, protected risczone, used by Sigma Designs only
4: audio microcode, protected risczone, used by Sigma Designs only
5: transport demuxmicrocode, protected risczone, used by Sigma only
6: irqhandler running on xpu, xpuzone, used by Sigma Designs only
7: xtask2, xpuzone, used for Sigma Designs DRM implementations.
8: xtask3, xpuzone
9: xtask4, xpuzone
0xff: xosupdate


The Certificate 0< ID < 2048 is a ID which uniquely identifies each Certificate issued by Sigma Designs
