117 / 129 page  DocID024767 Rev 4 117/129 L99PM72GXP ST SPI 128 6.2.22 Global status register The Global Error Flag is set once the watchdog failure counter (SR3<7:4>) is unequal to 0 (see also Section 2.5: Fail Safe Mode). Table 132. Global status register Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Hex value Active high/low High High Low High High High High High Default value in Normal Mode - after correct WD trigger or after Read & Clear on Error Flags 00100 000 20 Power ON 10000 000 80 Power ON weak battery (7) 10000 010 82 Communication error 11000 000 C0 VS overvoltage or undervoltage 10100 010 A2 WD failure 10100 001 A1 SPI Error (DI Stuck) 10100 001 A1 TSD1 10101 000 A8 TSD2 10111 001 B9 V1 Fail 10100 100 A4 Other Device Failure(8) 10100 000 A0 1. The following Status Bits are reported in the Global Error Flag: Global Status Register: Bits 6-0 Status Register 1: Bits 10-0 Status Register 3: Bits 15, 11, 7-2 2. Communication Error: invalid number of CLOCK cycles during CSN low or failed parity check on standby command. 3. Cleared with CLR command on SR3. 4. Cleared with “READ and CLEAR” on SR3 (-> TSD1) 5. Diagnosis bit only, VS Fail is not a Fail-Safe event; cleared by Read&Clear. Bit is automatically cleared at (VS >VSUV) and (VS < VSOV) if Vlock_out_en = 0 6. Cleared with a valid WD trigger (WD fail) or by clearing the corresponding status register related to failure. It is recommended that the microcontroller does not enter standby mode, if a fail-safe event is indicated in the Global Status Register. The selective wake-up configuration in CR 7 to 15 has to be re-written before sending the standby command. 7. Slow VS ramp-up (VS undervoltage is filtered with 64µs after power-on reset) 8. The Global Error Flag is raised due to a failure condition which is not reported in the Global Status Register. The Failure is reported in the Status Registers 1-5 |
