The ADC sequentiallysamples one of the eight channels per ping group (thenumber of ping groups per ensemble is the maximum of theWP). These fields are zeroed at the beginning of the deploymentand updated each ensemble at the rate of onechannel per ping group. For example, if the ping group sizeis 5, then:END OF ENSEMBLE No. CHANNELS UPDATEDStart All channels = 01 0, 1, 2, 3, 42 5, 6, 7, 0, 13 2, 3, 4, 5, 64 7, 0, 8, 2, 3↓↓Here is the description for each channel:CHANNEL DESCRIPTION0 XMIT CURRENT1 XMIT VOLTAGE2 AMBIENT TEMP3 PRESSURE (+)4 PRESSURE (-)5 ATTITUDE TEMP6 ATTITUDE7 CONTAMINATION SENSORNote that the ADC values may be “noisy” from sample-tosample,but are useful for detecting long-term trends.Contains the long word containing the bit flags for the CY?Command. The ESW is cleared (set to zero) between eachensemble.Note that each number above represents one bit set – theymay occur in combinations. For example, if the long wordvalue is 0000C000 (hexadecimal), then it indicates that botha cold wake-up (0004000) and an unknown wake-up(00008000) occurred.Low 16 BITSLSBBITS 07 06 05 04 03 02 01 00x x x x x x x 1 Bus Errorx x x x x x 1 x Address Errorx x x x x 1 x x Illegal Instructionx x x x 1 x x x Divide by Zerox x x 1 x x x x Emulatorx x 1 x x x x x Unassignedx 1 x x x x x x Not Used1 x x x x x x x Not UsedLow 16 BITSMSBBITS 15 14 13 12 11 10 09 08x x x x x x x 1 Pingingx x x x x x 1 x Not Usedx x x x x 1 x x Not Usedx x x x 1 x x x Not Usedx x x 1 x x x x Not Usedx x 1 x x x x x Not Usedx 1 x x x x x x Cold Wakeup1 x x x x x x x Unknown Wakeuppage 70Teledyne RD Instruments
