6.4 Watchdog Timer Refresh Register (0x60D)

Any write access to this register reloads the Watchdog Timer (WDT). This must be
done periodically after the WDT is enabled to keep the WDT from causing a
board reset.

Any read access returns 0x00.

6.5 Watchdog Timer Control and Status Register LS Byte (0x60E)

6.6 Watchdog Timer Control and Status Register MS Byte (0x60F)

6.7 Board ID String Registers (0x610 to 0x61A)

These read back ASCII values for “SBC347A”, as follows:
