IrDA Pulse Mode/Width Register
The ASC IrDA pulse mode and width register PMW contains the 8-bit IrDA pulse width
value and the IrDA pulse width mode select bit. This register is only required in the IrDA
operating mode.

IrDA Pulse Width Value
PW_VALUE is the 8-bit value n, which defines the
variable pulse width of an IrDA pulse.
Depending on the ASC input frequency f_ASC, this
value can be used to adjust the IrDA pulse width to
value which is not equal 3/16 bit time (e.g. 1.6 ms).
