These registers are accessible only when LCR[7] = 0.
These bits in can only be modified if register bit EFR[4] is enabled.
These bits are reserved and should be set to 0.
Only available on the SC16IS750/SC16IS760.
After Receive FIFO or Transmit FIFO reset (through FCR[1:0]), the user must wait at least 2
Burst reads on the serial interface (that is, reading multiple elements on the I
without de-asserting the CS pin), should not be performed on the IIR register.
These registers are accessible only when MCR[2] = 1 and EFR[4] = 1.
IrDA mode slow/fast for SC16IS760, slow only for SC16IS750.
The special register set is accessible only when LCR[7] = 1 and not 0xBF.
