T11 is a nice addition, but it seems to lack a feed from XOSC ?

That means you cannot calibrate an operating HIRC from a crystal, you need to reconfigure SYSCLK to XOSC, then measure HIRC, then restore SYSCLK to HIRC.
That disturbs SYSCLK, whilst another MUX connection could have avoided that.

Are there any limits on T11 clock ratios ?
eg can SYSCLK of 11.0592MHz from XOSC, read a 44MHz HIRC OK ?

Also, T11 has 16b-RELOAD but no 16b-CAPTURE mode ?

您好,最新版本手册中没有找到STC8H2K08U的管脚图,ISP软件中也没找到这个型号的封装脚位,请问是删掉了么?这个型号应该是属于STC8H2K12U系列,完全跟STC8H2K12U一样么?
