pulldown resistor for devices that are to be powered off.
Summary: GPIO_CS1–GPIO_CS0: Built-in pullup and pulldown resistors that are invoked by:
Reset invokes pullup.
When enabled as the GPIO_CS1–GPIO_CS0 signals:
can be left as inputs with pullups for a Suspend when the serial device is left powered. Or, they can be configured as inputs
with pulldown resistors if the serial device is to be powered off (Power-Down Group D).
Summary: The serial port output pins have built-in pulldown resistors that are invoked by Suspend mode.
Summary: The serial port input pins have built-in pullup and pulldown resistors that are invoked by:
is three-state with a built-in pulldown resistor, and the input has a built-in pulldown resistor. The pulldown resistor on the input
pin (SIRIN) can be programmed to be disabled during normal operation and Suspend mode.
Summary: The serial infrared input pin has a built-in pulldown resistor that is invoked by:
–Reset invokes the pullup resistors.
–Operating: the pullup resistors are enabled.
–Suspend mode invokes the pulldown resistors if the serial interface is programmed to be powered off in Suspend (Power-
–Reset invokes the pulldown resistor.
–The pulldown resistor is then programmable to be there or not.
Down Group C); otherwise there are pullup resistors in Suspend mode.
As an output, the pullup and pulldown are disabled in all modes, and these GPIO_CSxs can be active in Suspend.
As an input, the pullup can be programmed to be enabled or disabled; this will then be the state of the pin in all modes,
including Suspend.
