Main PLL Group Register Descriptions Contains registers with settings for the Main PLL. Offset: 0x40 vco Contains settings that control the Main PLL VCO. The VCO output frequency is the input frequency multiplied by the numerator (M+1) and divided by the denominator (N+1). The VCO input clock source is always eosc1_clk. Fields are only reset by a cold reset. misc Contains VCO control signals and other PLL control signals need to be controllable through register. Fields are only reset by a cold reset. mpuclk Contains settings that control clock mpu_clk generated from the C0 output of the Main PLL. Only reset by a cold reset. mainclk Contains settings that control clock main_clk generated from the C1 output of the Main PLL. Only reset by a cold reset. dbgatclk Contains settings that control clock dbg_base_clk generated from the C2 output of the Main PLL. Only reset by a cold reset. mainqspiclk Contains settings that control clock main_qspi_clk generated from the C3 output of the Main PLL. Only reset by a cold reset. mainnandsdmmcclk Contains settings that control clock main_nand_sdmmc_clk generated from the C4 output of the Main PLL. Only reset by a cold reset. cfgs2fuser0clk Contains settings that control clock cfg_s2f_user0_clk generated from the C5 output of the Main PLL. and user documentation refer to cfg_s2f_user0_clk as cfg_h2f_user0_clk. Only reset by a cold reset. en Contains fields that control clock enables for clocks derived from the Main PLL. 1: The clock is enabled. 0: The clock is disabled. Fields are only reset by a cold reset. maindiv Contains fields that control clock dividers for main clocks derived from the Main PLL Fields are only reset by a cold reset. dbgdiv Contains fields that control clock dividers for debug clocks derived from the Main PLL Fields are only reset by a cold reset. tracediv Contains a field that controls the clock divider for the debug trace clock derived from the Main PLL Only reset by a cold reset. l4src Contains fields that select the clock source for L4 MP and SP APB interconnect Fields are only reset by a cold reset. stat Contains Output Clock Counter Reset acknowledge status.
