Figure 18. Clock summary table
This tool also supports a degree of code generation. Summary provides two sample clock initialization
functions, Sysclk_Init for configuring oscillators and PLLs and InitPeriClkGen for providing
sources/dividers to auxiliary clocks. The dynamic C code in these functions depend on tool settings just
like the register summary. These functions can be copied and pasted to a source file via Ctrl+C/Ctrl+V
or by clicking on the associated Copy Code button, if macros are enabled. The following figure shows
Sysclk_Init and its Copy Code button.
