Description:

Controls the method of clearing the encoders fast position latch.

Mode Description

0 always re-capture position. Using this mode the data within the fast position register

will be updated on every activating edge on the appropriate fast interrupt line. The

latch is cleared automatically.

1 do not re-capture position until after the handler has completed. Using this mode the

data in the fast position register will remain unchanged whilst in the user installed

handler. When this handler exits the latch will automatically be cleared and enable

further latching. If a users handler has not been defined then the latch will be processed

as soon as the interrupt has been serviced.

2 do not re-capture position until the latch has been cleared manually. Using this mode

the register will remain unchanged until the user clears the latch manually using

FASTENABLE.

3 Disables the fast position latch for that axis.
