Legend
A[3:0] = Address bits.
DR[3:0] = I/O enabled as outputs (1 = enabled as output).
Legend
A[3:0] = Address bits. The address of the selected device. An
address value of “0000” is ignored by all devices.
Legend
A[3:0] = Address bits. The slave address.
V[2:0] = Device version number. The silicon version number of the
device. For this device the device type is 00011 as indicated by the
lowest bits.
Legend
A[3:0] = Address bits. The address of the selected device. An
address value of “0000” clears all devices.
