This register and DOGTHD1[11:0] are defined to an expired threshold for

internal watchdog counter. The threshold {[DOGTHD1, DOGTHD0] is a 28-bit

value. To multiply 28-bit value with one-cycle period of a host clock is the

expired duration. If the DOGEN is set to ‘1’ and WDTEI of ISR is set, then

AX88780 will periodically generate interrupt whenever the counter reaches to the

threshold.
