This filter is implemented using a combination of hard-
ware and software resources. Hardware is used to accu-
mulate the high-speed in-coming data while the software
is used to process the lower speed, enhanced resolution
data for output.
Decimator Incremental Register (DEC_CR, Address = Bank 0, E6h)
Decimator High Register (DEC_DH / DEC_CL, Address = Bank 0, E4h)
Decimator Data Low Register (DEC_DL, Address = Bank 0, E5h)

8-bit data value when read is the high order byte within the 16-bit decimator data registers
Any 8-bit data value when written will cause both the Decimator Data High (DEC_DH) and Decimator Data Low
(DEC_DL) registers to be cleared
