Design Tips
Question 1:
Answer 1:
Ensure that you are using the correct SPI mode for that device. This SPI supports all four SPI
modes so you should be able to get it to function. Check the clock polarity and the clock phase.
Question 2:
Answer 2:
This SSP module does not have master mode fully automated in hardware, see Application Note
AN578 for software which uses the SSP module to implement master mode. If you require a fully
automated hardware implementation of I
for devices that have the Master SSP module.
Question 3:
Answer 3:
Ensure that you set the CKP bit to release the I
Note:
At the time of printing only the High-end family of devices (PIC17CXXX) have
devices with the Master SSP module implemented.
