USART support for BRG16?

The 16 bit SPBRG modes available on some of the more recent PICs provides incredible bit rate tolerances. Are there any plans to support the 16 bit SPBRG capability in the USART modules?

For those forum members who may be interested, you can download an SPBRG Calculator spreadsheet or a stand-alone program (pictured below) that provides 16-bit and legacy 8-bit SPBRG solutions from the following forum.microchip thread; Revised SPBRG Calc

This tool isn't really necessary when using Swordfish because the SPBRG solution is calculated automatically in the USART module but it's still quite handy for comparing bit error rates with different oscillator frequencies, baud rates, and USART configurations during the project design phase.

which devices have you been looking at?

'2420/'2520/'4420/'4520, for now.

Email me directly, I have a module you can test if you like...

David,

Just wanted to follow up and say thank you for the modified USART module. I haven't tried it on a PIC yet but the code looks as clever, simple, elegant, and intuitive as all your other code.
