@ Description
_8124_set_input_filter_enable:
This function is used to enable the digital filter. If the filter is
enabled, pulse width of input signals "EA, EB, EZ and LTC" must
larger than 100 ns or the input signal will be ignore (treat as a
noise).
This function is available after Firmware version: 0x13.
_8124_get_noise_detect:
This function is used to detected whether the signal is a noise or
not. If the width of input signal is less than 100 ns, the status will
be turned ON. The status will be cleared after read.
This function is available after Firmware version: 0x13.
_8124_get_pwm_trigger_count:
This function is used to get PWM trigged counter.
This function is only for debug used. Because It does not have
register latch protection (high word (16-31 bits) latch) of counter
when register read. Therefore, it could be a problem when counter
is count up at mean time you read the counter.
This function is available after Firmware version: 0x13.
_8124_reset_pwm_trigger_count:
This function is used to reset PWM triggered counter.
This function is available after Firmware version: 0x13.
