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.)
SLOT13
LATCH condition
SLOT14
LATCH condition
Serial DATA transmitting interval.:I T
soft-changing time:T

The order of the slot 14 becomes ineffective in the case as the upper figure.

(Note.1)
In to make the Serial DATA transmitting interval IT from MCU(microcomputer)to M61528FP
Serial DATA transmitting interval :
IT >
soft-changing time
: T
the reading error of the DATA doesn't occur.
DATA transmitting example
The DATA transmitting interval when it was set up with the Soft-changing time = 33mS(Internal oscillator using).
