QSPI Interface
Using the high-speed QSPI interface with CPOL = 0 and
CPHA = 0, the MAX11100 supports a maximum fSCLK
of 4.8MHz. Figure 11a shows the MAX11100 connected
to a QSPI master and Figure 11b shows the associated
interface timing.
PIC16 with SSP Module and PIC17 Interface
The MAX11100 is compatible with a PIC16/PIC17 micro-
controller (FC) using the synchronous serial-port (SSP)
module.
To establish SPI communication, connect the controller
as shown in Figure 12a. Configure the PIC16/PIC17 as
system master, by initializing its synchronous serial-port
control register (SSPCON) and synchronous serial-port
status register (SSPSTAT) to the bit patterns shown in
In SPI mode, the PIC16/PIC17 FC allows 8 bits of data
to be synchronously transmitted and received simultane-
ously. Three consecutive 8-bit readings (Figure 12b) are
necessary to obtain the entire 16-bit result from the ADC.
DOUT data transitions on the serial clock’s falling edge
and is clocked into the FC on SCLK’s rising edge. The
first 8-bit data stream contains all zeros. The second 8-bit
data stream contains the MSB through D8. The third 8-bit
data stream contains bits D7 through D0.
