    \ingroup  G_PERIPHERAL

    WDT(WatchDog) is a program to moniter every registered programs, and will restart these programs while thy are up and down.

    <b> Features </b>
    - 32-bit counter;
    - WDT clock uses live crystal clock;
    - Adjustable length of the WDT reset;
    - Interrupt asserted (if enabled) when counter hits the reg_wdt_int??
    - A flag for WDT tracking (un-touchable by global IP reset).

    \image html WDT.png

    <b> Usage </b>
    -# WDT on/off/restart:
        WDT will be enabled after system is turned-on;
        WDT will be disabled when set reg_wdt_max??to zero;
        WDT will be re-started when set reg_wdt_clr??
    -# Set  reg_wdt_max??for length of WDT period;
    -# Set  reg_wdt_int??to enable interrupt if needed;
        Interrupt asserted when "WDT counter [31:16]" is equal to reg_wdt_int??and "WDT counter[15:0]" is equal to 0x0000
    -# Set  reg_wdt_rst_len??to adjust the length of WDT reset.
    -# Read reg_wdt_rst_flag??to see if WDT reset ever happened.
