Default at power up = latch-in or Byte 0 Rom table. VCO Frequency = 14.318 x [NDiv(9:0)+8] / [MDiv(5:0)+2] Disable Enable 1160ms Base Writing to this register will configure how many bytes will be read back, default is 0F = 15 bytes. Writing to these bit will configure the safe frequency as Byte0 bit (4:0). - - B10b(4:0) These bits represent X*290ms (or 1.16S) the watchdog timer waits before it goes to alarm mode. Default is 7 X 290ms = 2s. 290ms Base 01 Disable Enable 01 Normal Normal Latch Inputs - - Alarm |
