QSPI Interface
Using the high-speed QSPI interface with CPOL = 0
and CPHA = 0, the MAX1067/MAX1068 support a
maximum f
SCLK
of 4.8MHz. Figure 21a shows the
MAX1067/MAX1068 connected to a QSPI master and
Figure 21b shows the associated interface timing.
PIC16 with SSP Module and PIC17
Interface
The MAX1067/MAX1068 are compatible with a PIC16/
PIC17 controller (μC), using the synchronous serial-port
(SSP) module.
To establish SPI communication, connect the controller
as shown in Figure 22a and 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 Tables 7 and 8.
In SPI mode, the PIC16/PIC17 μCs allow 8 bits of data to
be synchronously transmitted and received simultane-
ously. Three consecutive 8-bit-wide readings (Figure
22b) are necessary to obtain the entire 14-bit result from
the ADC. DOUT data transitions on the serial clock’s
falling edge and is clocked into the μC on SCLK’s rising
edge. The first 8-bit-wide data stream contains all zeros.
The 2nd 8-bit-wide data stream contains the MSB
through D6. The 3rd 8-bit-wide data stream contains bits
D5 through D0 followed by S1 and S0.
