Figure 6 Window watchdog timing definition
Figure 6 shows some guidelines for designing the watchdog trigger timing taking the
oscillator deviation of different devices into account. Of importance is the maximum
(w.c.) of the closed window and the minimum of the open window in which the trigger has
to occur.
The length of the OW and CW can be modified by SPI command. If a change of the
window length is desired during the Watchdog function is operating please send the SPI
command with the new timing with a ’Watchdog trigger Bit’ D15=1.In this case the next
CW will directly start with the new length.
A minimum time gap of > 1/48 of the actual OW/CW time between a ’Watchdog disable’
and ’Watchdog enable’ SPI-command should be maintained. This allows the internal
Watchdog counters to be resetted. Thus after the enable command the Watchdog will
start properly with a full CW of the adjusted length.
