This clock is identical to PLLSYSCLK, but is gated when the CPU selected by CPUSEL enters STANDBY mode based on individual STANDBYEN bit in respective peripheral system configuration register (PERxSYSCONFIG).
Each peripheral has a CPU selection logic to select either CPU1, CPU2, or CPU3 which is done by using the CPUSEL register. The CPU selection logic is only for clock gating purposes since there is no CPU to peripheral allocation and any CPU can access and configure any peripheral provided the respective CPU has access to it. Each peripheral clock also has an independent clock gating that is controlled by the CPU PCLKCRx and STANDBYEN registers.
By default, the ePWM, EMIF, and LIN clocks each have an additional /2 divider, which is required to support CPU frequencies over 100MHz. At slower CPU frequencies, these dividers can be disabled using the PERCLKDIVSEL register.
