51 microcontrollers/microprocessors and the serial I2C-bus.
54 Communication with I2C-bus is
55 carried out on a byte-wise basis using interrupt or polled handshake.
57 controls all the I2C-bus specific sequences, protocol, arbitration and timing.
58 The PCF8584 allows parallel-bus systems to communicate bidirectionally with
59 the I2C-bus.

54 The device has 8 general purpose I/O pins and an I2C controller that supports
55 a subset of the I2C protocol.
58 An output pin can be configured either for open-drain or push-pull operation.
59 Pins 0, 1 and 7 support special functions: I2C transmit indication,
60 I2C receive indication and clock output respectively.
65 The I2C controller supports read transactions with up to 512 bytes of data,
