mountain999 Question

Feb 28, 2019 00:00

I am trying to perform SPI communication in non-DMA mode.

However, no interrupt is received after reception.

I write the register and value that I set up below

Are you missing the setting? Or is it wrong?

Please confirm.

SPI0_CTL = 0x0431
SIZE = 10b
CPOL = 1b
CPHA = 1b
EN = 1b
SPI0_TXCTL = 0x0100
TDU = 1b
SPI0_RXCTL = 0x005D
RDR = 101b
RWCEN = 1b
RTI = 1b
REN = 1b
SPI0_STAT = 0x0400
RF = 1b
SPI0_IMSK_SET = 0x0400
RF = 1b

Besides this, setting of Priority and Handler is done.

Best regards
