LIMP0 electrical characteristics...continued 19.6.5 LIMP0 release When the fail-safe outputs LIMP0 is asserted low by the device because of a fault, some conditions must be validated before allowing LIMP0 pin to be released by the device. These conditions are: • No fault affecting LIMP0 reported • Fault error counter = 0 • Device in Normal mode • Device not in INIT mode • FS_FS0B_LIMP0_REL register filled with the correct value, depending on current WD_TOKEN[15:0] value as per Table 57. 19.6.6 LIMP1, LIMP2 Two additional pseudo-safety output can be used when configuring general purpose I/Os or high-side drivers as LIMP1 or LIMP2 functions. HVIO1, LVIO3, or HS1 can be configured as LIMP1 function and HVIO2, LVIO4, or HS3 can be configured as LIMP2 function. When used, LIMP1 and LIMP2 are following LIMP0 assertion, except when requested from the MCU. LIMP1 and LIMP2 paths can also be checked by the MCU by requesting their assertion by SPI/I2C. When asserted, LIMP1 and/or LIMP2 will be released when LIMP0 is released. If LIMP0 is already released (that is, LIMP1 or LIMP2 was asserted after MCU request), a LIMP0 release request must be sent by the SPI to release them. LIMP1 and LIMP2 can work as asserted to a static level (high or low), or as PWM (configurable polarity) when asserted, depending on LIMPx_CFG[1:0] bit.
