communication on FlexWire. The watchdog timer is programmable by a 4-bit register WDTIMER for 13 options.
The timer in TPS929160-Q1 starts to count when there is no instruction received from the master controller.
The TPS929160-Q1 enters FAIL-SAFE states when the timer overflows. The device can be also forced into
FAIL-SAFE states anytime in NORMAL state by setting FORCEFS to 1. The FORCEFS register automatically
returns to 0.
7.4.4 FAIL-SAFE state
When the TPS929160-Q1 is entering FAIL-SAFE state from NORMAL state, all the registers are set to default
value or reloaded from EEPROM.
The Flexwire interface keeps alive in FAIL-SAFE state. Setting FORCEFS to 1 forces the device into FAIL-SAFE
state from NORMAL state. The TPS929160-Q1 can quit from FAIL-SAFE state to NORMAL state by setting
CLRFS to 1 with FLAG_FS register cleared.
7.4.5 PROGRAM state
The TPS929160-Q1 can enter EEPROM PROGRAM state by writing multiple configuration registers to
EEPGATE and setting 1 to EEPMODE. For details of getting into PROGRAM state, refer to EEPROM
Programming.
