would like to know in what pin the UART comes programmed from factory, in the PAN1740 design guide application note v.1.6 i see
on page 8, schematic shows UART is connected to P0.0(RX), P0.1(TX),
on page 36, schematic shows UART is connected to P0.4(TX), P0.5(RX). Why ?
Datasheet on PA1740 reports as in page 36. But a note(*) says the pin can also be programmed in a different way.
What does this mean ?
Also, looking with oscilloscope on P0.4(TX), P0.5(RX) is see a strange burst of data that's not rs232. Is this a propertary protocol ?
