In PSoC® 6, how can I route the internal clock out to a pin for other purposes?
For all PSoC 6 parts, the output of CLK_HF  (or CLK_HF ) can be routed out through P0 or P0. All internal source clock (IMO, ECO, EXTCLK, BLE ECO, ILO, PLIO, WCO, Digital Signal) can be routed to CLK_HF (or CLK_HF ) through internal clock path, so you can get any internal source clock directly (or 2/4/8 divided) from either the P0 or the P0 pin.
The method of routing the internal clock out to a pin in PSoC Creator is simple:
Configure the required internal source clock to CLK_HF and choose a suitable divider value.
Drag a clock component and choose CLK_HF as the source in the clock component.
Drag a Digital Output pin component and assign P0 or P0 to the component. Connect the clock and pin component.

For PSoC 6 parts with UDB resource, there is another way to route CLK_HF out to a pin through UDB/DSI resource. The output pin is not limited to P0 or P0 only, any GPIO pin is fine.
Figure 2 shows the TopDesign schematic.

Note: In PSoC Creator, P0 and P0 are also dedicated EXT_CLK pins; if either P0 or P0 is used as EXT_CLK pin, the other pin can be used for clock output.
In ModusToolBox 2.0, it is same easy to route internal clock resource out to P0 or P0 pin, just by config the clock editor. For example, if you want to route intrenal WCO clock out to P0, they you can just config the clock editor of ModusToolBox like below:
