Digital Interface
Input (control byte) and output data are multiplexed on
a three-state parallel interface. This parallel interface
(I/O) can easily be interfaced with standard μPs. The
signals
CS
,
WR
, and
RD
control the write and read
operations.
CS
represents the chip-select signal, which
enables a μP to address the MAX1290/MAX1292 as an
I/O port. When high,
CS
disables the CLK,
WR
, and
RD
inputs and forces the interface into a high-impedance
(high-Z) state.
Input Format
The control byte is latched into the device on pins D7–
D0 during a write command. Table 2 shows the control
byte format.
Output Format
The output format for the MAX1290/MAX1292 is binary in
unipolar mode and two’s complement in bipolar mode.
When reading the output data,
CS
and
RD
must be low.
When HBEN = 0, the lower 8 bits are read. With HBEN =
1, the upper 4 bits are available and the output data bits
D7–D4 are set either low in unipolar mode or to the value
of the MSB in bipolar mode (Table 5).
