ETL Watchdog Killer

An external watchdog suppressor for the MC9S12(X) Microcontrollers.
  • In many cases, In-circuit MCU access is blocked by an external watchdog.
  • The 'Reset' pin must be lifted up to gain access to MCU.
  • The ETL 'Watchdog Killer' fix this obstacle.
  • It pools 'Reset' pin up to +5V during all program/read cycle.
  • NOTE: Only use the 'Watchdog Killer' if external watchdog is active and the 'MC9S12(X) Freescale Microcontrollers' software detects it.
