Modified SPI Interface Description
The SCLK, DIN, and DOUT of the MAX15500/MAX15501
assume standard SPI functionality. While the basic func-
tion of the MAX15500/MAX15501 CS_ inputs is similar
to the standard SPI interface protocol, the management
of the CS_ input within the chain is modified. When both
CS_ inputs are low, the MAX15500/MAX15501 assume
control of the DOUT line and continue to control the line
until the data frame is finished and READY goes low
(Figure 9). Once a complete frame is processed and the
READY signal is issued, the devices do not accept any
data from DIN, until either CS1 or CS2 rises and returns
low. A new communication cycle is initiated by a sub-
sequent falling edge on CS1 or CS2. When either CS1
or CS2 is high, the MAX15500/MAX15501 SPI interface
deactivates, DOUT returns to a high-impedance mode,
READY (if active) clears, and any partial frames not yet
processed are ignored.
READY asserts once a valid frame is processed allowing
the next device in the chain to begin processing the sub-
sequent frame. A valid frame consists of 16 SCLK cycles
following the falling edge of CS_. Once READY asserts,
it remains asserted until either CS_ rises, completing the
programming of the chain.
