Other Parts Discussed in Thread: TCA6416A
Hi,
I've several question for initial setting for TCA9535. Could you please give me your help?
1. Is there recommend sequence for setting register? e.g. Polarity Inversion Port 0→Polarity Inversion Port 1→Configuration Port 0→Configuration Port 1
2. How should user set I2C Fast mode? Is there a specific bit to set Fast or Standard mode?
3. Power-on-reset time: How long will POR take in the case of VDD = 1.8V? e.g Master MCU should wait ?? us after power on.
Regards,
Nagata.
