i am a beginner in learning the TS201, and one problem confused me, in the function: "builtin_sysreg_write(reg, int) ", before the parameter reg, we need to add underscore before the register name? why... i can't understand
the register names require underscores as that is, by default, how they are defined in "...\TS\include\sysreg.h". As you will see from that header file, you can add a preprocessor definition "__NOUNDERSCORES__" so that the register names are defined without the "__".
