[2] This bit can only be modified if register bit EFR[4] is enabled. [3] These bits are reserved and should be set to logic 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] These registers are accessible only when EFR[4] = logic 1, and MCR[2] = logic 1. [7] These registers apply to both channels. [8] IrDA mode slow/fast for SC16IS762, slow only for SC16IS752.
