# Addressor

## Init Args

<ParamField path="address_bits" type="int" />

## Parameters

<ParamField path="address" type="dimensionless" />

<ParamField path="base" type="dimensionless" />

<ParamField path="offset" type="dimensionless" />

## Interfaces

<ParamField path="address_lines[0]" type="ElectricLogic" />

## Global Attributes

These attributes are available to all modules and interfaces in a design.

<ParamField path="lcsc_id" type="str">
  Assign the LCSC ID of the module.

  If set, this will tell the picker to select that part from LCSC for this block.
</ParamField>

<ParamField path="manufacturer" type="str">
  This module's manufacturer name, as a string.

  Only exact matches on the manufacturer's name will be found by the picker.
  It's recommended to fill this information based on what `ato create component`
  provides.
</ParamField>

<ParamField path="mpn" type="str">
  This module's manufacturer part number, as a string.

  For the picker to select the correct part from the manufacturer,
  this must be set.
</ParamField>

<ParamField path="package" type="str">
  The package of the module.

  This drives which components can be selected, and what footprint is used.

  Must exactly match a known package name.
</ParamField>

<ParamField path="exclude_from_bom" type="bool" />

<ParamField path="override_net_name" type="str">
  When set on an interface, this will override the net name of the interface.

  This is useful for renaming nets which are automatically generated.
</ParamField>

<ParamField path="required" type="bool">
  Only for ModuleInterfaces.
  If set to `True`, require that interface is connected to something outside
  of the module it's defined in.
</ParamField>

<RequestExample>
  ```ato Basic Usage theme={null}
  import Addressor, I2C, ElectricPower

  # For I2C device with 2 address pins (4 possible addresses)
  addressor = new Addressor<address_bits=2>
  addressor.base = 0x48  # Base address from datasheet

  # Connect power reference for address pins
  power_3v3 = new ElectricPower
  for line in addressor.address_lines:
      line.reference ~ power_3v3

  # Connect address pins to device
  device.addr0 ~ addressor.address_lines[0].line
  device.addr1 ~ addressor.address_lines[1].line

  # Connect to I2C interface
  i2c_bus = new I2C
  assert i2c_bus.address is addressor.address
  device.i2c ~ i2c_bus
  ```
