11.4.11. Debug Clocks
Arm* Clock Name |
Clock Source |
HPS Clock Signal Name |
Description |
---|---|---|---|
ATCLK | Clock manager |
dbg_at_clk | Trace bus clock. |
CTICLK (for csCTI) |
Clock manager |
dbg_at_clk | Cross trigger interface clock for csCTI. It can be synchronous or asynchronous to CTMCLK. |
CTICLK (for FPGA-CTI) | FPGA fabric |
fpga_cti_clk | Cross trigger interface clock for FPGA‑CTI. |
CTICLK (for CTI-0 and CTI-1) |
Clock manager |
mpu_clk | Cross trigger interface clock for CTI‑0 and CTI‑1. It can be synchronous or asynchronous to CTMCLK. |
CTMCLK (for csCTM) |
Clock manager |
dbg_clk | Cross trigger matrix clock for csCTM. It can be synchronous or asynchronous to CTICLK. |
CTMCLK (for CTM) | Clock manager |
mpu_clk | Cross trigger matrix clock for CTM. It can be synchronous or asynchronous to CTICLK. |
DAPCLK | Clock manager |
dbg_clk | DAP internal clock. It must be equivalent to PCLKDBG. dbg_clk must be at least twice as fast as the JTAG clock. |
PCLKDBG | Clock manager |
dbg_clk | Debug APB* (DAPB) clock. |
HCLK | Clock manager |
dbg_clk | Used by the AHB* -Lite master inside the DAP. It is asynchronous to DAPCLK. In the HPS, the AHB* -Lite port uses same clock as DAPCLK. |
PCLKSYS | Clock manager |
l4_mp_clk | Used by the APB* slave port inside the DAP. It is asynchronous to DAPCLK. |
SWCLKTCK | JTAG interface FPGA fabric
Note: There are two clock sources.
|
dap_tck tpiu_traceclkin
Note: There are two signal names.
|
The SWJ-DP clock driven by the external debugger through either the JTAG interface or the FPGA fabric. It is asynchronous to DAPCLK. When through the JTAG interface, this clock is the same as TCK of the JTAG interface. |
TRACECLKIN | Clock manager |
dbg_trace_clk | TPIU trace clock input. It is asynchronous to ATCLK. In the HPS, this clock can come from the clock manager or the FPGA fabric. |
