Figure 6. Detailed Serial-Interface Timing
The ADC serial interface operates with just SCLK, DIN,
and DOUT (allow sufficient time for the conversion to
complete between read/write operations). Achieve con-
tinuous operation by connecting BUSY to an uncommit-
ted P I/O or interrupt, to signal the processor when the
conversion results are ready. Figures 8a and 8b show
the timing for SPI/MICROWIRE and QSPI operation.
The fully static 16-bit I/O register allows infinite time
between the two 8-bit read/write operations necessary
to obtain the full 16 bits of data with SPI and
MICROWIRE. CS must remain low during the entire
two-byte transfer (Figure 8a). QSPI allows a full 16-bit
data transfer (Figure 8b).
Interfacing to the 80C32 Microcontroller Family
Figure 7c shows the general 80C32 connection to the
MAX110/MAX111 using Port 1. For a more detailed dis-
cussion, see the MAX110 evaluation kit manual.
I/O Shift Register
Serial data transfer is accomplished with a 16-bit fully
static shift register. The 16-bit control word shifted into
this register during a data-transfer operation controls
the ADC’s various functions. The MSB (NO-OP)
enables/disables transfer of the control word within the
ADC. A logic 1 causes the remaining 15 bits in the con-
trol word to be transferred from the I/O register into the
control register when CS goes high, updating the
ADC’s configuration and starting a new conversion. If
