3.2 Power-Up into Normal Mode in SPI Control

Figure 3-2 shows the power-up sequence when starting the TLIN1431-Q1 in SPI control, with the PIN/nCS pin either high-impedance or pulled high to VCC.

Figure 3-2 SPI Control Power-Up Sequence Timing

To transition to normal mode, the device must first transition from INIT mode through restart mode and standby mode.
