117 / 444 page  Peripherals The LDETECT signal is by default not connected to the GPIO port's DETECT signal, but via the DETECTMODE register it is possible to change from default behavior to DETECT signal being derived directly from the LDETECT signal instead. See GPIO port and the GPIO pin details on page 116. DETECT signal behavior on page 117 illustrates the DETECT signal behavior for these two alternatives. PIN0.DETECT 1 PIN1.DETECT PIN31.DETECT DETECT (Default mode) DETECT (LDETECT mode) 3 4 2 LATCH.0 LATCH.1 LATCH.31 Figure 40: DETECT signal behavior The input buffer of a GPIO pin can be disconnected from the pin to enable power savings when the pin is not used as an input, see GPIO port and the GPIO pin details on page 116. Inputs must be connected to get a valid input value in the IN register, and for the sense mechanism to get access to the pin. Other peripherals in the system can connect to GPIO pins and override their output value and configuration, or read their analog or digital input value. See GPIO port and the GPIO pin details on page 116. Selected pins also support analog input signals, see ANAIN in GPIO port and the GPIO pin details on page 116. The assignment of the analog pins can be found in Pin assignments on page 416. Important: When a pin is configured as digital input, care has been taken to minimize increased current consumption when the input voltage is between VIL and VIH. However, it is a good practice to ensure that the external circuitry does not drive that pin to levels between VIL and VIH for a long period of time. 6.8.2 Registers Base address Peripheral Instance Description Configuration 0x50000000 GPIO P0 General purpose input and output Table 37: Instances Register Offset Description OUT 0x504 Write GPIO port 4454_140 v1.0 117 |
