Tool/software:
Hi, experts:
I used CCS Theia 1.3.1 to set uart configure of 20 WQFN in LP-MSPM0C1104, if I set RX PA22/TX PA23, connect PA22 to a logic analyzer, then send test data like "0x00 0x55 0xB1" to PA22, works well, but if I changed RX to PA28, sent the same test data to it, the data captured in logic analyzer is other value with frame error, so I wonder what's the cause? Thanks.test_uart.rar
