◆ tms570_system_hw_init()

void tms570_system_hw_init ( void )

TMS570 system hardware initialization (HCG:systemInit)

Set up flash address and data wait states based on the target CPU clock frequency The number of address and data wait states for the target CPU clock frequency are specified in the specific part's datasheet.
Configure the LPO such that HF LPO is as close to 10MHz as possible
Wait for PLLs to start up and map clock domains to desired clock sources
