Reading from this register takes the next byte from the receive FIFO and clears the overrun error bit if it was set. In UART mode (SC1 only), reading from this register loads the UART status register with the parity and frame error status of the next byte in the FIFO, and clears these bits if the FIFO is empty. 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 Reserved 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Reserved MODE[1:0] rw rw Bits [31:2] Bits [1:0] This bit-field specifies the serial control operating mode 00: No mode selected 01: UART mode 10: SPI mode 11: I2C mode Note: If the UART mode is supported only by SC1 |
