MAX3421E
USB Peripheral/Host Controller
with SPI Interface
21
Maxim Integrated
1) The SPI master sets the clock to its inactive state.
While
SS is high, the master can drive the MOSI pin
to any value.
2) The SPI master selects the MAX3421E by driving
SS low and placing the first data bit (MSB) to write
on the MOSI input.
3) The SPI master turns on its output driver and clocks
the command byte into the MAX3421E on the rising
edges of the SCLK it supplies. The SPI master
changes its MOSI data on the falling edges of SCLK.
4) After eight clock cycles, the master can drive
SS
high to deselect the MAX3421E.
5) To write SPI data, the SPI master keeps its output
driver on and clocks subsequent bytes into the
MOSI pin. To read SPI data, after the eighth clock
cycle the SPI master tri-states its output driver and
begins clocking in data bytes from the MOSI pin.
6) The SPI master terminates the SPI cycle by return-
ing
SS high.
Figures 10 and 11 show timing diagrams for full- and
half-duplex operation.
