CCS/TMS320F28375D: CPU1/CPU2 processing speed setting.

Part Number: TMS320F28375D


Tool/software: Code Composer Studio

Please tell me about the processing speed setting of the core.

[environment]
-TMS320F28375D
-CCS 8.1.0.00011

A dual environment is used.
The PLL is set using InitSysPll in InitSysCtrl on CPU1.
The PLL is not changed by other processing.
      InitSysPll (XTAL_OSC, IMULT_20, FMULT_0, PLLCLK_BY_2);

In this state, use an oscilloscope to check the processing speed of CPU1 and CPU2.
It seems that CPU1 is operating at 200Mhz and CPU2 is operating at 100Mhz.

Why doesn't CPU2 run at 200MHz?
