NP5 CANopen Technical Manual

3231h Flex IO Configuration

Function

Defines how the pins (inputs/outputs 1 … 4) of the device are used.

Each bit in the respective subindex corresponds to a pin, whereby the first pin configures DIO1, the second pin DIO2, etc.

  • Pin 1: DIO1_IO_CS
  • Pin 2: DIO2_CD_CLK
  • Pin 3: DIO3_CD_DIR
  • Pin 4: DIO4_IO_MOSI
  • Subindex 03h Alternate Function Mask: This bit mask defines whether the alternative function of the pin is to be activated.

    To activate an alternative function, set the corresponding bit to "1":

    Bit Pin Alternative function
    1 DIO2_CD_CLK Clock input in clock-direction mode
    2 DIO3_CD_DIR Direction input in clock-direction mode
    Note:

    If you do not activate the alternative function, you can no longer use the corresponding pin as a normal input/output.

    If the Clock-direction mode is activated, the pins for clock and direction are automatically configured accordingly and the settings in 3231h are overwritten.

  • Subindex 01h Output Mask: This bit mask defines whether the pin is used as input or output (depending on whether an alternative function was activated for the pin in subindex 03h):
    • Bit = "0": Pin is input (default)
    • Bit = "1": Pin is output
  • Subindex 02h Pullup Mask: This bit mask defines whether the pin is a pullup or pulldown:

    • Bit = "0": Pin is pulldown (default)
    • Bit = "1": Pin is pullup

    Subindex 02h is only active for the pin if it is defined as an input.

Example for subindex 01h: Pin 2 and pin 3 are to be outputs, value = "6" (=0110 b)
