The nINT shares the pin with the SPI serial data output (SDO) function and is defaulted as SDO only. If the pin is to be used as nINT, register 8'h29 should be set to 1b, SDO_CONFIG. When configured to support nINT,the pin functions as an interrupt output when the nCS pin is high and by default is pulled low for a global interrupt, 8'h50[7:0]. When nCS is low the device is using the SPI ports and this pin is the serial data output from the TCAN114x-Q1. Figures Figure 10-6 and Figure 10-7 show an example high level system and timing diagram when using the nINT feature.
