always_zero    0x80000000

Sign bit; always zero.

bump_up_ccw_sticky    0x40000000

The windscreen touched. Only valid for altitude (up) or azimuth (anticlockwise)

bump_dn_cw_sticky    0x20000000

The windscreen touched. Only valid for altitude (down) or azimuth (clockwise)

ms_on_correction_too_large    0x01000000

The correction made by an MS.ON command would have exceeded MS.MAX

clock_slow_signal    0x00020000

Unused

clock_loss_signal    0x00010000

Failed to see the GPS interrupt

semCmdPort_taken    0x00004000

Someone else has the semCmdPort semaphore (and is thus permitted to use the mcpMenu to move the telescope)

stop_in    0x00002000

A stop button has been pushed.

amp_bad    0x00001000

The amplifier for this axis is not OK

out_closed_loop    0x00000800

This axis is out of closed loop

stop_ok    0x00000400

A stop button has not been pushed (masked).

amp_ok    0x00000200

The amplifier for this axis is OK (masked).

closed_loop    0x00000100

This axis is in closed loop (masked).
