IrDA RZ Pulse Width
Controls pulse width of TX ‘0’ data. If PW = 3, the high
pulse has duration of 3/16 of it’s a bit period or 3 * 3686400^-
1 _sec.
The IrDA shares data path with UART. So all of UART registers such as baud rate,
interrupt en/disable, communication control, line status also influence to IrDA mode.
