ByteN Read data starting at ADDR. ADDR auto-increments until SPI_CSZ is raised. Upon completion, SPI_CMD (SFR 0xFD) is updated to 1xxx xxxx and an SPI interrupt is generated. The exception is if the command byte is 1000 0000. In this case, no MPU interrupt is generated and SPI_CMD is not updated. ADDR 0xxx xxxx STATUS Byte0 ... ByteN Write data starting at ADDR. ADDR auto-increments until SPI_CSZ is raised. Upon completion, SPI_CMD is updated to 0xxx xxxx and an SPI interrupt is generated. The exception is if the command byte is 0000 0000. In this case, no MPU interrupt is generated and SPI_CMD is not updated. |
