Hello,
As described in PN7160 Datasheet, 11.2.2.2 SPI-bus configuration options:
In order to select SPI-bus interface for host communication, some EEPROM settings are
programmed during production.
Four versions can be configured depending on CPOL/CPHA EEPROM setting.
The selection between interfaces is fused during IC manufacturing so that different
ordering numbers for the SPI-bus version.
I have not found any information on different ordernumbers that affect the settings.
Is this an error?
Thanks,
Michael

Hello sir,
Unfortunately, the datasheet needs an update. The PN7160 is configured as follows:
CPHA=0
IFSEL1=0
I hope this information may have been useful.

I think only I2C vs SPI is programmed during manufacturing. Part number ending with "A" is I2C and "B" is SPI. Clock polarity can be changed later
