319 CHSG Settings group change
IRIG-B Control Bits, Time-Error Calculation Bits and SNTP Bits
320 YEAR80 IRIG-B year information, binary-coded decimal, add 80 if asserted
320 YEAR40 IRIG-B year information, binary-coded decimal, add 40 if asserted
320 YEAR20 IRIG-B year information, binary-coded decimal, add 20 if asserted
320 YEAR10 IRIG-B year information, binary-coded decimal, add 10 if asserted
320 YEAR8 IRIG-B year information, binary-coded decimal, add 8 if asserted
320 YEAR4 IRIG-B year information, binary-coded decimal, add 4 if asserted
320 YEAR2 IRIG-B year information, binary-coded decimal, add 2 if asserted
320 YEAR1 IRIG-B year information, binary-coded decimal, add 1 if asserted
321 TUTCH Offset half-hour from UTC time, binary, add 0.5 if asserted
321 TUTC8 Offset hours from UTC time, binary, add 8 if asserted
321 TUTC4 Offset hours from UTC time, binary, add 4 if asserted
321 TUTC2 Offset hours from UTC time, binary, add 2 if asserted
321 TUTC1 Offset hours from UTC time, binary, add 1 if asserted
321 TUTCS Offset hours sign from UTC time, subtract the UTC offset if TUTCS is asserted, add otherwise
322 DST Daylight-saving time
322 DSTP Daylight-saving time pending
322 LPSEC Direction of the upcoming leap second. During the time that LPSECP is asserted, if LPSEC is
asserted, the upcoming leap second is deleted; otherwise, the leap second is added.
322 LPSECP Leap second pending
322 TQUAL8 Time quality, binary, add 8 when asserted
322 TQUAL4 Time quality, binary, add 4 when asserted
322 TQUAL2 Time quality, binary, add 2 when asserted
322 TQUAL1 Time quality, binary, add 1 when asserted
323 LOADTE Load TECORR Factor (SEL
OGIC Equation). When a rising-edge is detected, the accumu-
lated time-error value TE is loaded with the TECORR factor (preload value).
323 STALLTE Stall time-error calculation (SEL
OGIC equation). When asserted, the time-error calcula-
tion is stalled, or frozen.
323 PLDTE Asserts for approximately 1.5 cycles when the TEC command is used to load a new
time-error correction factor (preload value) into the TECORR analog quantity.
