Post by thread:[PIC] PIC32MX575F512H SPI 8 Bit Slave Mode

Has anyone out there worked with the PIC32MX575F512H part? Specifically using its SPI module in slave mode. I have it setup to act as a slave, 8 bit mode, with SS enabled. When bursting 250 bytes from a master to the 575 part, all bytes are received okay, but the part is skipping bytes sending back to the master. The transmit empty buffer interrupt is only generating an interrupt every 16 spi clock cycles (it acts as if the transmit portion is stuck in 16 bit transfer mode). I'm NOT using the enhanced buffer mode. I have the code working fine on the smaller PIC32MX150F128D part and have reviewed the errata sheet for the 575 part for any anomalies with the SPI module (none that apply to my situation). I have also reported this problem to Microchip (no word back yet). So, does anyone know if there is or might be a problem in the firmware of the 575 part? Thanks, Ross
