6.10.5 Receiving the FIFO Data Register for Infrared Remote Control Signals (IRRRFDR)
Address: 0x00B4 Initial value: 0x00
D7
IRRRDR_D7 IRRRDR_D6
R
This register is an 8-bit FIFO register for storing received data. All the received data can be obtained from this register
until it is emptied. For details, refer to 6.1.8, "Infrared Remote Control Data Structure."
6.10.6 Transmitting the FIFO Data Register for Infrared Remote Control Signals (IRRSFDR)
Address: 0x00B5 Initial value: 0x00
D7
IRRSDR_D7 IRRSDR_D6
W
This register is an 8-bit FIFO register that stores transmission data. Transmission data can be stored until this register is
filled with data. For details, refer to 6.10.8, "Infrared Remote Control Data Structure."
6.10.7 RTC/Touch Panel/Key Input/Power Supply Status Register (RTKISDR)
