21.1 REMC Configuration

The S1C17001 incorporates a remote controller (REMC) module for generating infrared remote control commu-
nication signals. The REMC module consists of a carrier generation circuit for generating a carrier signal using
the prescaler output clock, an 8-bit down-counter for counting the transferred data length, a modulation circuit for
generating transmission data of the specified carrier length, and an edge detection circuit for detecting input signal
rising and falling edges.
The module is also capable of generating counter underflow interrupts indicating that the specified data length has
been transmitted and input rising/falling edge detection interrupts for data receipt processing.
Figure 21.1.1 shows the REMC module configuration.
