6.3.5.1 Windowed Watchdog Circuits
The TPS99001-Q1 contains two windowed watchdog circuits that can be used to detect malfunctions within the DLPC23x-Q1.
Figure 6-6 Windowed Watchdog FunctionThe DLPC23x-Q1 software uses both watchdog circuits. Watchdog #1 (WD1) monitors the internal microprocessor of the DLPC23x-Q1 through a wire connection to a dedicated GPIO line from DLPC23x-Q1. Watchdog #2 (WD2) is used to monitor the DLPC23x-Q1 sequencer operation (through monitoring of the SEQ_STRT pin, wired to WD2 input).
When this function is enabled, two registers control the timing of the opening and closing of a watchdog trigger window. Process is initiated by a rising edge on the respective WDx pin. If another rising edge occurs before the WD trigger window opens, a watchdog error is issued. If the end of the open window period is reached without receiving a rising edge on WDx, an error is issued. The process restarts any time a WDx rising edge is received. The two watchdogs are independent.
