Note 1: fc: High-frequency clock [Hz]
Note 2: After reset, RPOLS do not change the set value in the receiving remote control signal. For setting interrupt
Note 1: fc: High-frequency clock [Hz]
Note 2: When an interrupt source is set for rising/falling edge, low and high widths are forcibly measured
Note 3: Set CREGA (0H to FH) before EINT sets to 8-bit receive end.
