Description
CNTINH:L X X X X X X Changes take effect after the
second byte is written.
Effect is seen after the next TOF or
PWM synchronization.
MODH:L 0 0 X 1 0 X MODH:L are updated with their write
buffer contents when the counter
reaches its maximum value after the
enabled hardware or software
trigger has occurred.
0 0 X 0 1 X MODH:L are updated with their write
buffer contents when the counter
reaches its minimum value after the
enabled hardware or software
trigger has occurred.
0 1 X X X X MODH:L are updated with their write
buffer contents when the enabled
hardware or software trigger occurs.
1 X X 1 0 X MODH:L are updated with their write
buffer contents when the counter
reaches its maximum value after the
enabled software trigger has
occurred.
1 X X 0 1 X MODH:L are updated with their write
buffer contents when the counter
reaches its minimum value after the
enabled software trigger has
occurred.
