CY - Clear Error Status Word

Purpose Clears the Error Status Word (ESW) stored in EEPROM on the CPU. The ESW is updated
whenever an error occurs.
Format CYn
Range n = 0 (Clear), 1 (Display)
Format Use the CY1 command to display the ESW value or CY0 to clear the ESW.
Recommended Setting. Use as needed.
Description CY1 displays the active ESW value, which is a 32-bit value displayed in Hex ASCII.

In the command mode, the Error Status Word (ESW) codes can be cleared through the CY-command. In
ping mode, the ESW is cleared (set to zero) between each ensemble. The values are logically OR'ed. For
example, if an illegal instruction (xxx4) and a divide by zero error (xxx8) occurred since the last time the
ESW was cleared, a value of "xxxC" would appear as the ESW.
ESW code 0x0000100 can only be seen if the CY-command is issued between CS-commands in
the manual ping mode. This flag is used to determine if on wakeup, whether the H-ADCP was
pinging or not previous to the present power up. A CS-command sets this bit; a <BREAK> resets
the bit. This results in the following consequences:
a) A deployment must be ended with a <BREAK>. If the H-ADCP is pinging, and power is lost,
when power is restored, the H-ADCP will continue to ping.
