22. Remote Control Signal Receiver
22.1 Introduction
The remote control signal receiver has two circuits for checking the width and period of an of external
pulse.
Table 22.1 lists Remote Control Receiver Specifications, Figure 22.1 to Figure 22.3 show remote control
signal receiver block diagrams, and Table 22.2 lists the I/O Ports.
