Wrong data message on SC18IM700

Question asked by Rúben Marques on Jun 29, 2018

Hi there,

I'm having a issue regarding some UART messages on SC18IM700.

I send, for example, the folowed message by UART:

0x53 0x40 0x02 0x55 0x55 0x50 0x52 0x0A 0x50

That message works properly. I have a PCF controller with 0x40 address. I receive 0xF0 and can see the outputs changed.

In fact, all kind of messages works well, unless when I need to send a 0xFF (eg: 0x53 0x40 0x02 0xFF 0xFF 0x50 0x52 0x0A 0x50). In that case the SC18IM700 doesn't send anything by I2C (I confermed by osciloscope, and nothing hapens on I2C lines).

Any ideas?
