'[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?
