Tool/software:
Hi Champs,
I am using M0C1103 as an I2C I/O expander. The package is SOT-16, so the PA1/SDA is merged with NRST. Thus I guess the RC reset circuit may affect the I2C waveform.
May I confirm if the pull up resistor of 47K and capacitor of 10nF (recommended RC values for reset circuit: https://www.ti.com/lit/an/slaaeg4/slaaeg4.pdf) work well with I2C normal mode? How about Fast mode?
Regards,
Kien Nguyen
