Applications Information
Connection to Standard Interfaces
The MAX1284/MAX1285 serial interface is fully compat-
ible with SPI/QSPI and MICROWIRE (Figure 11).
If a serial interface is available, set the CPU
’
s serial interface
in master mode so the CPU generates the serial clock.
Choose a clock frequency up to 6.4MHz (MAX1284) or
4.8MHz (MAX1285).
1) Use a general-purpose I/O line on the CPU to pull
CS
low. Keep SCLK low.
2) Activate SCLK for a minimum of fifteen clock cycles.
The first two clocks produce zeros at DOUT. DOUT
output data transitions 20ns after the third SCLK rising
edge and is available in MSB-first format. Observe the
