TMS320F28379D: CPU2 Clock/PLL

Matt Serwinowski

Part Number: TMS320F28379D

Greetings,

According to Clock Source figure 2.5, is the clock for CPU2 derived from CPU1? If CPU1 is initialized to run at 200MHz with PLL, then does CPU2 inherit that? Or must CPU2 receive the PLL on it's own? I've been diving into the documentation and SysCtrl.c, but I wanted to verify.

Best,

Matt

    Hi Matt,

    The clock derived from the PLLSYSCLK is given to both CPU1 and CPU2.

    But since the CPU1 has clock registers ownership access on default, the CPU1 does the configurations needed. 

    If PLLSYSCLK is clocked to run at 200MHz with PLL, then CPU2 & CPU1 both get it.

    Regards.
