Need 4 UARTS
I'm doing a master-slave communications project. The slaves are done and working, but the master needs four UARTS. So that means two SCB ones and twoUDB ones. They are all receive only. Should be no problem.
But it fails claiming to need 40 Macrocells and 82 Pterms. My calculations show it should need 24 macrocells.
I assume the discrepancy is that this is a bootable project (on a CY8CKIT-049-42xx. I presume that the bootloader is using a UDB UART.
The obvious solution would appear to be to "reuse" it. It isn't needed except when starting up in the bootloader.
Is there a way to do that? Can I make calls to configure it for my needs and repurpose it? I don't need interrupts.
