Pad control for all functional pads including:
— drive strength enable (DSE), via a control register
— pull enable (PUE), via a control register
— pull select (PUS), via a control register
Pin multiplexing and direction control for reset mode
Functional Mode
In this mode, the module drives each associated pin and has complete control of the direction of
that pin. The drive strength and pullup/pulldown enable are controlled via a set of control registers.
Reset Mode
In this mode, the pin configuration is changed for:
— clock output control: CLK_S0 and CLK_S1
— host interface control: IF_SEL0 and IF_SEL1
The control signals become available on the corresponding pins in reset mode. Refer to
