of
OMAP-based
8 LDO voltage regulators and one RTC LDO
applications.
(internal purpose)
Two of the step-down converters provide power for
One high-speed I2C interface for general-
dual processor cores and are controllable by a
purpose control commands (CTL-I2C)
dedicated class-3 SmartReflex interface for optimum
