4.2 Baud Rate Setting
Jumpers SEL0-2 and serial EPROM settings are used to set the host interface RXD and TXD data rate.
Note that this is independent of the IrDA connection data rate.
Data format is always 8 data bits, no parity, and 1 stop bit. Note that this is compatible with end-to-end
data format using 7 data bits, parity, and 1 stop bit. That is, the application at both end of the IrDA link
may generate and check parity if 7 data bit is used.
The Host Interface can operate on eight different baud rates from 1.2kbps to 115.2kbps.
SEL7 ~ SEL0 (D12 ~ D5):
1: None
0: Install DIODE (1N4148)
