* Welcome to the firmware code for the USRP Octoclock accessory product!
*
* Notes regarding this firmware:
* NOT in M103 compatibility mode
* CKOPT full rail-to-rail
* xtal osc
* 16K CK (16K clock cycles)
* additional delay 65ms for Crystal Oscillator
* slowly rising power
* persistent EEPROM
*
* These settings are very conservative. If a lower power oscillator is
* required, change CKOPT to '1' (UNPROGRAMMED).
*
* M103C = [ ]
* WDTON = [ ]
* OCDEN = [ ]
* JTAGEN = [X]
* SPIEN = [X]
* EESAVE = [X]
* BOOTSZ = 4096W_F000
* BOOTRST = [ ]
* CKOPT = [X]
* BODLEVEL = 2V7
* BODEN = [ ]
* SUT_CKSEL = EXTHIFXTALRES_16KCK_64MS

* EXTENDED = 0xFF (valid)
* HIGH = 0x81 (valid)
* LOW = 0xFF (valid)
