HARDWARE BASED LOCK PROTECTION FOR CRITICAL RESET CONTROL REGISTERS

摘要

Provided herein a hardware based lock protection for reset control registers to protect for reset control register, comprises a peripheral performing a particular task, a high capacity programmable logic device (HCPLD) for resetting the peripheral after being incited and a controller for inciting the high capacity programmable logic device (HCPLD) to reset the' respective peripherals. Therefore, the invention provides a high level of protection against wrong resetting of the peripheral due to software bugs or any other malfunction. Moreover, said protection is provided in the hardware level itself. Reference Figure 1.
