RCHITECTURAL
The Decoder Control circuit block is the users communications port. This circuit
converts the information from the control port into the internal control signals
required to establish the operating mode of the decoder.
The Z86230 responds to its slave address for both the
tions. If the
responds with an Acknowledge. The master should then send an address byte fol-
lowed by a data byte. If the
the Z86230 responds with an Acknowledge followed sequentially by a status byte
and a data byte.
addressing exhibits both indirect and direct modes. The busy bit in the status byte
indicates if the
The Voltage/Current reference circuit uses an externally connected resistor to
establish the reference levels that are used throughout the Z86230. For a minimal
investment, the use of an external resistor can also provide improved internal pre-
cision.
