6.2.5.1.1. Main Clock Domain
The main domain is largest synchronous domain in the interconnect, containing most of the datapath. The main domain generally consists of a single free-running clock and divided clocks with enables. Resets in the main domain depend on clock groups. Each clock group in the table below uses a single reset. Paths crossing different groups also cross asynchronous reset domains.
Group | Clock | Clock Divider | Reset | Usage |
---|---|---|---|---|
main | l3_main_free_clk | - | l3_rst_n | clocks most of the interconnect datapath |
l4_main_clk | 1 | DMAC and SPI | ||
l4_mp_clk | 2 | EMAC, SDMMC, NAND, USB, ECC | ||
l4_sp_clk | 4 | L4_SP bus | ||
l4_sys_clk | 4 | L4_SYS bus | ||
syscfg | l4_sys_clk | 4 | syscfg_rst_n | L4_SHR and L4_SEC buses |
dbg | cs_at_clk | 1 | dbg_rst_n | CoreSight |
cs_pdbg_clk | 2 | CoreSight |
