Required Configuration

CPU_CntLeadZeros()is available and implemented in cpu_core.c if CPU_CFG_LEAD_ZEROS_ASM_PRESENT is not #define'd in cpu_cfg.h (or cpu.h), but should be implemented in cpu_a.asm (or cpu_a.s) if CPU_CFG_LEAD_ZEROS_ASM_PRESENT is #define'd in cpu_cfg.h (or cpu.h). Refer to Core Library Configuration for details.

Each CPU_CntLeadZerosXX() is available and implemented in cpu_core.c based on CPU_CFG_DATA_SIZE_MAX configuration as #define'd in cpu.h :
