SPI Parameter

Figure 83:

SPI Characteristics

SPI Characteristic: Shows the key electrical parameter of the SPI interface.

PMW DVS Control Interfaces

Description

Two dedicated PMW interfaces can be used to perform DVS on

SD0 and SD6.

The voltage is determined by a base value (vpwmX_base) and

the increments according to the duty cycle of the pwm signal.

The step-size and reset behavior can be programmed

individually for both interfaces.

A threshold value of 0.6-to 1.84V can be set in the OTP to limit

the maximum allowed output voltage for each of the two

regulators.
