5.11 Latch

@ Name

@ Description

_8124_set_latch:

This function is used to enable or disable the high-speed posi-
tion capture (latch) function and set the latch condition. When-
ever the users enable it and configure the latch condition
(Rising or falling active) correctly, the current position will be
latched when it receive the latch signal. Users can check the
latch events by polling “_8124_get_latch_event_sts” or by
using the interrupt function. See also section 5.13 Interrupt
function.

_8124_get_latch_event_sts:

This function is used to check the latch event status. If the latch
function is enabled and the latch condition is met, the status
will become 1 from 0. The event status is read-clear.

_8124_get_latch_value:

When the latch event occurred, you can use this function get
the latched counter value.

@ Syntax
