It is possible to select the primary channel mode, secondary channel mode, and the primary channel as
well as the secondary channel according to the settings of R11 and R12.

It is possible to set the RS-232C communication speed with R13, R14, and R15.
However when the control line extension mode of R16 is not installed, the settings will be valid for all
self-channels. But, when it is 0R, if the R11 and R12’s IrDA mode setting is primary or primary /
secondary channel, then the self-channel with be valid. If it is set to the secondary channel, regardless of
the communication speed setting, the other device will set the communication speed. (Figure 2-2).
When the communication rate has established an IrDA link, it will be sampled, so it is okay to change the
speed settings while it is in operation. In the event that the speed is changed while communicating, the
current communication link will be severed and with any following communication the new speed will
become valid.
