Research direction

Start by reading DxCore's board and clock frequency definitions and compare them with the MegaCore or MiniCore implementations mentioned in the issue. Add support for 11.0592, 14.7456, 18.432, and 22.1184 MHz crystals; done means those frequencies are available for supported boards and existing build checks pass.

Description

Dear,

Is it possible to add the 'communication crystals' 11.0592MHz, 14.7456MHz, 18.432MHz and 22.1184MHz? I use them oft for correct RS232/RS485 communication without errors. MCUDude have them implemented in MegaCore, MiniCore, ....

Thanks in advanced.

Thanks for the great job.

Grts,

Theo
