6.10 Infrared Remote Control
This section describes the infrared remote control functions. Table 6.10 summarizes the infrared remote control
functions. For details of each register, refer to 6.10.1 to 6.10.8.
(1)
Support of formats for two kinds of infrared remote control signal
Supported format: NEC format and Home Appliance Manufacturer’s Association format
(2)
Function for receiving infrared remote control signals
• A maximum of 255 bytes of the infrared remote control signal can be stored. Receive data can be read from the
receiving FIFO data register (IRRRFDR).
• Infrared remote control signals of a specified format can be received.
• When a frame signal has been received, a receiving interrupt may be generated.
(3)
Function for transmitting infrared remote control signals
• A maximum of 255 bytes of the infrared remote control signal can be transmitted.
• Transmit data can be written to the transmitting FOFOI data register (IRRSFDR).
• Infrared remote control signals of the specified format are transmitted.
