Keys:
S = SIGN Bit
FT = FREQUENCY TEST Bit (Must be set to ‘0’ upon power for normal operation)
R = READ Bit
W = WRITE Bit
ST = STOP Bit
0 = Must be set to ‘0’
CEB = Century Enable Bit
CB = Century Bit
Note: When CEB is set to ‘1’, CB will toggle from ‘0’ to ‘1’ or from ‘1’ to ‘0’ at the turn of the century (dependent upon the initial value set).
When CEB is set to ‘0’, CB will not toggle.
The WRITE Bit does not need to be set to write to CEB and CB.
