Hello Kallikuppa-san,

Which description in 8.4.6.6 shows polarity change by mirror mode?

Thanks,

Koji Ikeda

Hello Koji Ikeda

Please refer below

Mirror mode can be enabled through strap or through register configuration using the Port Mirror Enable bit in the CFG4 register (address 0x0031). In Mirror mode, the polarity of the signals is also reversed.

Hello Kallikuppa-san,

"In Mirror mode, the polarity of the signals is also reversed." looks like to show no polarity change. Is this correct?

Thanks,
