Help Reading this
« on: September 23, 2013, 11:58:27 pm »
Okay maybe I'm an idiot and just missing it entirely.

I'm using this Micro-controller in my design:

http://ww1.microchip.com/downloads/en/DeviceDoc/39897c.pdf

I can't find the UART Pins or the SPI Pins!   I'm using the 100 pin TQFP package.  Can anyone point them out to me?  I thought the UART pins were labelled Ux but I can't find any.  The product webpages lists:

Digital Communication Peripherals   4-UART
3-SPI
3-I2C

Thanks

Andrew

It has remappable pins - a remarkable feature in those chips.

I know you can remap the pins, I'm trying to figure out what Pin's the UART and SPI are on.

Read section 10.4: Peripheral Pin Select...

Since those pins are "remappable", they are not associated particular pins - otherwise, they wouldn't be "remappable".
