R0P7727TH003TRKE General Information Manual

6.10.4 Transmit Data Count Register for Infrared Remote Control Signals (IRRSDNR)

Address: 0x00B3 Initial value: 0x00
D7 D6
IRRSD_D7 IRRSD_D6
R R
This register indicates the number of data items not transmitted (infrared remote control signals) stored in the
transmit FIFO register. When the value of this register is "0x00," it indicates that there is no data. When the
value of this register is "0xFF," it indicates that the transmit FIFO buffer is full of data.

6.10.5 Receive 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 6.10.8, "Infrared Remote Control Data Structure."

6.10.6 Transmit FIFO Data Register for Infrared Remote Control Signals (IRRSFDR)

Address: 0x00B5 Initial value: 0x00
D7 D6
IRRSDR_D7 IRRSDR_D6
W 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."
