24 / 43 page  AS8222 Datasheet - Detailed Descr i p ti on www.ams.com/eng/FlexRay/AS8222 Revision 1.0 23 - 42 7.9 System Description Figure 5. State Machine Diagram Notes: 1. This state diagram does not include all transitions, which are shown in Table 19. 2. Prefix of “WHILE” is an event and suffix in brackets checks the flags or in case of EN and STBN the input condition. - For example: VREC_VBAT WHILE (EN=0 AND STBN=0) - After the event VBAT supply voltage recovery is detected, the transition is performed if EN and STBN are “low”. UV_VBAT:Undervoltage event and/or flag for VBAT supply voltage UV_VIO:Undervoltage event and/or flag for VIO supply voltage UV_VCC:Undervoltage event and/or flag for VCC supply voltage VREC_VBAT:Voltage recovery event and/or flag for VBAT supply voltage WAKE:Wake event and/or flag VREC_VIO:Voltage recovery event and/or flag for VIO supply voltage VREC_VCC:Voltage recovery event and/or flag for VCC supply voltage Reset_Wake:Wake flag is set to low Reset_UV_VCC:Undervoltage flag VCC is set to low EN =1 AN D S TB N=0 EN= 0 A ND STB N=1 POWER-OFF RECEIVE-ONLY STANDBY SLEEP EN=0 WHILE (STBN=1) EN=1 WHILE (STBN=1) EN=0 AND STBN=0 OR UV_VCC UV_VBAT THEN (RESET_WAKE) OR UV_VIO THEN (RESET_WAKE) From any State (except Power Off) EN=0 WHILE (STBN=0) OR UV_VCC EN=1 WHILE (STBN=0) OR WAKE WHILE (EN=1 AND STBN=0) OR VREC_VCC WHILE (EN=1 AND STBN=0) Timer = tSLEEP WA KE WH ILE (EN =0 AN D S TB N= 0) OR VR EC _V BA T WH ILE (EN =0 AN D S TB N= 0) OR VR EC _V IO WH ILE (EN =0 AN D S TB N= 0) OR VR EC _V IO WH ILE (UV _V CC ) STBN=1 WHILE (EN=0) OR WAKE WHILE (EN=0 AND STBN=1) OR VREC_VBAT WHILE (EN=0 AND STBN=1) OR VREC_VIO WHILE (EN=0 AND STBN=1) Input: EN = 0 STBN = 1 Output: INH1 = 1 INH2 = 1 Input: EN = x STBN = 0 Output: INH1 = float INH2 = float UV_VBAT WHILE (UV_VCC) OR UV_Vcc WHILE (UV_VBAT) WAKE WHILE (EN=0 AND STBN=0) OR UV_VCC WHILE (EN=0 AND STBN=0) OR VREC_VCC WHILE (EN=0 AND STBN=0) OR WHILE (UV_VCC) (EN=0 OR EN=1) OR (STBN=1 OR STBN=0) WHILE (UV_V BAT OR UV_VIO) OR UV_VBAT OR UV_VIO OR UV_V CC OR VREC_VCC NORMAL Input: EN = 1 STBN = 1 Output: INH1 = 1 INH2 = 1 GO-TO-SLEEP Input: EN = 1 STBN = 0 Output: INH1 = 1 INH2 = float Input: EN = 0 STBN = 0 Output: INH1 = 1 INH2 = float EN= 1 AN D ST BN= 1 OR WAK E WH ILE (EN= 1 AN D ST BN= 1) TH EN (Res et_U V_V CC) OR V REC_V CC W HILE (EN= 1 AN D ST BN= 1) |
