52 / 230 page  NXP Semiconductors FS23 Safety system basis chip (SBC) with power management, CAN FD and LIN transceivers configured slot starts. See Figure 29 as an example of HVIO pins configuration, with HVIO1 default state low and assigned to power sequence slot 1, and HVIO2 default state high assigned to power sequence slot 2. aaa-051451 VBAT HVIO1 (default 0) HVIO2 (default 1) OTP Loaded Slot 0 Tslot Tslot Tslot Slot 1 Slot 2 Vsup > Vsup_UV Figure 29. Example of HVIO pins configuration in the slots, at power up HVIO1 and HVIO2 pins can also be configured respectively as LIMP1 and LIMP2 pseudo-safety outputs. These functions come in addition to LIMP0 safety output pin, and are described in detail in Section 19.6.6. 15.2.3 Electrical characteristics TA = −40 °C to 125 °C, unless otherwise specified. VSUP = 5.5 V to 40 V, unless otherwise specified. All voltages referenced to ground.

HVIO12 electrical characteristics [1] There is no digital filtering when HVIOx input pin is used as a source to control an high-side driver. 15.3 LVIO3, LVIO4, LVI5, LVO6 The LVIO3 and LVIO4 pins are low-voltage digital input/output. They can be used as digital input as wake-up sources for the device, or as digital outputs. The MOSI/LVI5 pin can only be used as digital input, and MISO/LVO6 can only be used as digital output.
