Hi,
Refer to reference manual RM0029 Page1362, while using eSCI as UART mode,
1) for SCI data register eSCI_DR,what's meaning for two lines below 15:0(R), 0:15(W)?
2) while bit sequence D0->D7(10101101) received on UART_RXD line (bit order is D0->D7), how data
stored in eSCI_DR register?
a) eSCI_DR[7:0] = D[0:7](10101101)
b) eSCI_DR[7:0] = D[7:0](10110101)
which one is correct,why?
Thanks in advanced.

Yes , the RM is not clear
I would take
eSCI_DR[7:0] = D[7:0](10110101)

Hi, Erwan
May I confirm item 1)
What is digitial 15-0 of R, and digital 0-15 of W?
Does digital 0 Most Significant Bit, and digital 15 means least Significant Bit ?
