epc110  
Parameter settings can be done by writing complete 16 bit registers only.  
Bits marked up in white fields shall be modified or programmed only. Gray marked bits with a given value in the memory map above must be  
set to this. Never change the memory content of gray marked cells without numeric indication. Writing to this cells is not allowed.  
The RAM can be written only, if the corresponding ROM memory hasn’t been written before (FUSEBIT = 0) or if the volatile mode is active  
(VMODE = 0). The first bit of each 16-bit ROM register serves as write inhibit bit (FUSEBIT). To write to the ROM, the micro-controller has to  
write the data to the RAM first (with FUSEBIT = 0). From there, the micro-controller can first double check the data integrity. When a memory  
section is verified, the content can be transferred from the RAM memory to the ROM using the command PROG (refer to chapter Command  
PROG). While processing this instruction the FUSEBIT will be set to “1” by epc110.  
The device is fully operational as well without programming the ROM, but data will be lost at power down. Operating the chip in this mode is  
helpful during the development of the product or if your application needs an adaptive mode. However, in the final application for a standalone  
or self-reboot operation, the parameters must be stored into the ROM memory.
