PN7150 I2C communication specification by version

[welpo]

When initializing PN71506 version chip and PN71501 version chip with the same code

It is confirmed that the I2C communication READ TIME of PN71501 version chip takes a little longer.

(The 06 version is read for 30ms, while the 01 version is not read for 30ms, causing an error in the same code. The 01 version is read if you change the READ TIME to 40ms).

Is there any difference between versions regarding I2C communication interval ?

I would be grateful if you could also let me know the minimum communication interval when communicating with i2c 400kHz.
