TMD4903 − ApplicationInformation
Controls associated to define the number of complete pattern
loops and sub-pattern repeats are: Number of Repeated
Sub-pattern Loops and Number of Complete Pattern Loops.
As depicted below, the number of “run-once” pattern loops sets
the amount of additional iterations, up to 254. If the register is
set to 0xFF then the sub-pattern is continuously repeated until
the value is changed or IBEN bit is reset.

Complete Pattern Loops: The red box represents a “run-once” pattern. The pattern begins at pattern ram
address 0x00 and bursts until the end of the pattern is encountered. The complete pattern can be reiterated 1 to
254 times, or continuously.
As depicted below, the number of repeated sub-pattern loops
sets the amount of additional “repeated part” burst iterations,
up to 254. If the register is set to 0xFF then the sub-pattern is
continuously repeated until the value is changed or IBEN bit is
reset.
