 ### Constructor
 
 - **MCP23S08(uint8_t select, uint8_t dataIn, uint8_t dataOut, uint8_t clock, uint8_t address = 0x00)** constructor SOFTWARE SPI.
-- **MCP23S08(uint8_t select, SPIClassRP2040\* spi)** constructor HARDWARE SPI with explicit SPI interface selected.
+- **MCP23S08(int select, SPIClassRP2040\* spi)** constructor HARDWARE SPI with explicit SPI interface selected.

+- **MCP23S08(int select, int address = 0x00, SPIClass\* spi = &SPI)** constructor HARDWARE SPI with optional address pins and SPI interface.
-- **bool begin()** returns true if successful.
+- **bool begin(bool pullup = true)** initializes library, returns true if successful. 
+Default sets the pins to INPUT PULLUP.
+Returns false if not connected or a register could not be set.
 - **bool isConnected()** returns true if connected, false otherwise. (dummy for compatibility reasons)
 - **uint8_t getAddress()** returns the address set in the constructor. 
 Default = 0, range = 0..3.
