I was looking over The schematic documentation And I found what looks like to me A technical error can someone please explain it to me

Txd is connected to rxd0 and rxd is connected to txd0
Is that how it is supposed to be or is the documentation wrong

This wll always be the case when you have two ends of a serial/uart connection. Data flows in one direction only on each of the two lines. So on each, one device/chip is transmitting, and the other is receiving. The other line flows in the opposite direction. TXD0 and RXD0 are from the perspective of the MCU, while TXD and RXD are pin functions on the CP2104 chip.
