Figure 27. QSPI Serial Interface Timing (CPOL = CPHA = 0)
PIC16 and SSP Module and PIC17 Interface
The AS1524/AS1525 are compatible with a PIC16/PIC17 controllers, using the synchronous serial port (SSP) module
To establish SPI communication, connect the PIC16/PIC17 controllers as shown in
Figure 28
and configure the PIC16/
PIC17 as system master. This is done by initializing its synchronous serial port control register (SSPCON) and syn-
chronous serial port status register (SSPSTAT) to the bit patterns shown in
Table 6 on page 18
and
Table 7 on
page 18
.
Figure 28. SPI Interface Connections for PIC16/PIC17 Controller
In SPI mode, the PIC16/PIC17 processor allow 8 bits of data to be synchronously transmitted and received simultane-
ously. Two consecutive 8-bit readings
(see Figure 29)
are necessary to obtain the entire 12-bit result from the AS1524/
AS1525. DOUT data transitions on the serial clock’s falling edge and is clocked into the processor on SCLK’s rising
edge.
The first 8-bit data stream contains the first 8 data bits starting with the MSB. The second data stream contains the
remaining bits, D3 through D0.
