4.6 Infrared port
One infrared RX port and one TX port (as shown in Figure 6) are connected to ACMP0 input pin
(ACMP0_IN1) and SCI0 TXD0 pin of KE02Z to demonstrate the capability of SCI0 modulated by
Flextimer for generating infrared signals and use ACMP0 as a filter to receive the SCI data via infrared
signal.
