width of 3/16 of the bit time. The ASC_P also allows to program the length of the IrDA
high pulse. Further, the polarity of the received IrDA pulse cane be inverted in IrAD
mode.

15.1.5.2 Asynchronous Transmission
Asynchronous transmission begins at the next overflow of the divide-by-16 baudrate tim-
er (transition of the baudrate clock f
loaded into S0TBUF. The transmitted data frame consists of three basic elements:
• the start bit
• the data field (8 or 9 bits, LSB first, including a parity bit, if selected)
• the delimiter (1 or 2 stop bits)
Data transmission is double buffered. When the transmitter is idle, the transmit data
loaded into S0TBUF is immediately moved to the transmit shift register thus freeing
S0TBUF for the next data to be sent. This is indicated by the transmit buffer interrupt re-
quest line S0TBIR being activated. S0TBUF may now be loaded with the next data, while
transmission of the previous one is still going on.
The transmit interrupt request line S0TIR will be activated before the last bit of a frame
is transmitted, ie. before the first or the second stop bit is shifted out of the transmit shift
register.
The transmitter output pin TXD must be configured for alternate data output’.
