[2] These bits in can only be modified if register bit EFR[4] is enabled. [3] These bits are reserved and should be set to 0. [4] After Receive FIFO or Transmit FIFO reset (through FCR[1:0]), the user must wait at least 2 T clk of XTAL1 before reading or writing data to RHR and THR, respectively. [5] Burst reads on the serial interface (that is, reading multiple elements on the I2C-bus without a STOP or repeated START condition, or reading multiple elements on the SPI bus without de-asserting the CS pin), should not be performed on the IIR register. [6] Only available on the SC16IS750/SC16IS760. [7] These registers are accessible only when MCR[2] = 1 and EFR[4] = 1. [8] Device returns NACK on I2C-bus when this bit is written. [9] IrDA mode slow/fast for SC16IS760, slow only for SC16IS750. [10] The special register set is accessible only when LCR[7] = 1 and not 0xBF.
