Data Transmission and the Relation of the Soft-Changing Time
This IC has the function which should make the following Serial DATA ineffective to the soft-changing movement
completion after LATCH condition detection.
(At the time of a slot 13 and the slot 14 transmission of the DATA input format.)
• In to make the Serial DATA transmitting interval IT from MCU(microcomputer)to M61528FP
• DATA transmitting example
Rev.1.1, Dec.17.2003, page 17 of 30
the reading error of the DATA doesn't occur.
The DATA transmitting interval when it was set up with the Soft-changing time = 33mS(Internal oscillator using).
soft-changing time is set up.
