Description
Input voltage supply can come from battery (VIN_BAT) or from
external power supply (VIN_PHX).
Emulates a door switch as an example in cyclic sense
configuration, by default for HVIO1, possible to change to HVIO2.
Configures the VSUP as input for WAKE1 pin (global).
Emulates a door switch as an example in cyclic sense
configuration, by default on WAKE2, possible to change to WAKE1.
Enables LED signaling for safety pins values when ON (on bottom
side).
Enables OTP DC-DC 8 V generator (see J30).
Enables safety I/Os and LVIOs signal propagation between FS23
and MCU when ON (see silkscreen).
Enables OTP mode if OTP DC-DC enabled, else enables DBG
mode (see J30).
Pushing button to reset S32K144 MCU.
