"V15.15 10/12/2011: Changes made necessary for the new Si570 chip from SiLabs.
** The new chip version with 7ppm temperature stability did change the
** Index of the RFREQ registers from 7 to 13. Also a new function to
** freeze the RFREQ when updating new data to the RFREQ (Freeze-M).
** The firmware can auto-detect the new Si570 chip and use the correct
** RFREQ index. The function CMD_SET_SI570_GRADE (0x44) is extended to
** support the change of RFREQ index.
** Also removed some global register variables to normal ram."
