J607 Watchdog Configuration
The phyCORE-LPC2292/94 supports a processor-independent
MAX6301 watchdog device, which can be configured with the help of
Jumper J607. This jumper configures various watchdog operating
modes with preconfigured settings or using a controller port pin to
change the mode.
The following configurations are possible:
Watchdog J607
MAX6301 configured for extended mode (
see IC data
sheet for details
), WDS pin via pull-up resistor, disables
watchdog due to floating WDI signal
open*
Additional logic ICs monitor the level of these /BOOT,
/DEBUG and RESET signals. If one of the signals has a
low level, then the WDT is disabled allowing unlimited
use of the phyCORE module. Following RESET
(without active low signals /BOOT and /DEBUG) the
WDT is always enabled if Jumper J607 is closed.
