This counter is programed by register 8'h28[7:4] which sets the number of times restart can be entered before transitioning to sleep or fail-safe mode, up to 14 times but should be programmed for greater than 1 to avoid possible loops. The default value is 4. Register 8'h28[3:0] is the counter. To prevent the transition to sleep or fail-safe mode, the counter should be cleared periodically. Entering sleep mode or fail-safe mode due to a meeting the restart counter automatically clears the restart counter.
