To generate baud rate for IrDA, use baud-rate generator in SIO0 by setting 01
The infra-red pulse width is specified either baud rate T × 3/16 or 1.6 µs (1.6 µs

; Set the SIO to UART mode.
; Set the receive data pulse width to 16×.
; TXEN, RXEN Enable the Transmission and receiving.
; The modem operates as follows:
• SIO0 starts transmitting.
• IR receiver starts receiving.
