89 / 176 page ST10F272M System reset Doc ID 12968 Rev 3 89/176 20.5 Watchdog timer reset When the watchdog timer is not disabled during the initialization, or serviced regularly during program execution, it will overflow and trigger the reset sequence. Unlike hardware and software resets, the watchdog reset completes a running external bus cycle if this bus cycle either does not use READY, or if READY is sampled active (low) after the programmed wait states. When READY is sampled inactive (high) after the programmed wait states the running external bus cycle is aborted. Then the internal reset sequence is started. Bit P0.12...P0.8 are latched at the end of the reset sequence and bit P0.7...P0.2 are cleared (that is written at ‘1’). A Watchdog reset is always taken as synchronous: there is no influence on watchdog reset behavior with RPD status. In case bidirectional reset is selected, a watchdog reset event pulls RSTIN pin low: this occurs only if RPD is high; if RPD is low, RSTIN pin is not pulled low even though bidirectional reset is selected. Refer to figures Figure 25 and Figure 26 for unidirectional SW reset timing, and to figures Figure 27, Figure 28 and Figure 29 for bidirectional. Figure 25. SW/WDT unidirectional reset (EA = 1) |
