buffer memory (Addresses 0

)) for the QD62(E/D).
2)
At the start (OFF to ON) of the preset command (voltage applied to the preset
input terminal), the preset value in the preset value setting buffer memory is
preset in the present value storage buffer memory. Preset can be executed
regardless of whether the count enable command {Y04(Y0C)} is ON or OFF.
POINT
While the external preset request detection flag {X04(X0B)} is ON (3), preset
cannot be executed even if voltage is applied to the preset input terminal or the
preset command {Y01(Y09)} is turned ON. Preset can be performed by turning ON
(4) the external preset request detection reset command {Y05(Y0D)} and turning
OFF the external preset request detection flag.
