TCAN1145-Q1: The SPI pins mode after TCAN1145-Q1 is powered-up

Ted Xu

Part Number: TCAN1145-Q1

HI BU team

Whether are all the SPI pins -nCS, SDI, SCLK, SDO high impedance when TCAN1145-q1 is powered-up if no any external terminals at these 4 pins?

What's the default mode on nCS after power up? Default high?

Thanks

Ted,

The SPI pins are high impedance until a SPI command is executed, in which case nCS is driven low. When nCS is in a logic-high state, the rest of the SPI pins are high-impedance, and the default mode on nCS is logic high.
