AD_MD2~0 - Advanced UART/Infrared mode Select.
These registers are active when Advanced UART Select (ADV_SL, in Set2.Reg2.Bit0) is
set to 1. Operational mode selection is defined as follows. When the backward operation
occurs these register will be reset to 0 and backward legacy UART mode.
SIR_PLS - Send Infrared Pulse
Write to 1 then automatically sends a 2
order to notify SIR that the high speed infrared is still in process when this pulse is sent.
This bit will be automatically cleared by hardware.
Not used.
TX_WT - Transmission Waiting
If this bit sets to 1, the transmitter will wait for TX FIFO to reach threshold level or
transmitter time-out which avoids short data bytes to want to transmit, before beginning to
transmit data from TX FIFO. This is in order to avoid Underrun.
Not used.
