When debugging and viewing the IOCON register in the memory window, the 64 pin part should offer a number of options for routing the UART Rx pin (e.g. [FONT="]PIO1_17) not available on the 48 pin package[/FONT]. When working with the 64 pin part, however, we've only seen the UART Rx pin options for the 48 pin version.
How are the different packages selected? Is the package determined at download time when the Chip ID is read?
Thanks!
