Figure 12a. SPI Interface Connection for a PIC16/PIC17
PIC16 with SSP Module and
PIC17 Interface
The MAX1162 is compatible with a PIC16/PIC17 micro-
controller (µC) 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
Tables 1 and 2.
In SPI mode, the PIC16/PIC17 µC allows 8 bits of data
to be synchronously transmitted and received simulta-
