Well, the CPLD neither knowns nor cares what's actually doing the programming - whether it's a dedicated programmer, a PC, a microcontroller, or whatever.
"All" (sic) you need to do is apply the correct signals in the correct sequences with the correct timing... Quite possibly, these details will be available from the CPLD manufacturer - I've seen a few Application Notes that describe doing such things. SO your first step is to do some research on the manufacturer's site for the specific chip of interest... |

| Things of the sort can be done... | 01/01/70 00:00 | |
| Why do you need to do that? | 01/01/70 00:00 | |
| Maybe... | 01/01/70 00:00 | |
| absolutely! But I'm still curious ... | 01/01/70 00:00 | |
