CU bit gets a high level and the current value of the
counter plus 1.The bit of CD is converted from 0 to 1 and
the current value minus 1. When the current value is
greater than or equal to the preset value, the counter bit
opens.The maximum value of the counter is 32767, and
the minimum value is -32768.When R gets a high level, the
counter is restored.
Counter range
:
C xxx=C0~C255
Attention: The counter number of each counter is different.
