Function
D[7..6]
Reserved
Write 0 when writing. 0 is returned after read.
D[5]
TMICMODE
Specifies the mode of the emitter or receptor module.
D[4]
TMICTX
Specifies the communication rate.
1 : Communication at 4 Mbps
0 : Communication at 1.15 Mbps or less
D[3..2]
IRMSEL[1..0]
Sets the type of emitter/receptor module to be used
11 : RFU
10 : HP model (HSDL-1100 is assumed)
01 : TEMIC model (TFDS6000 is assumed)
00 : SHARP model (RY5FD01D is assumed)
D[1]
IRUSESEL
Selects SIU or FIR for use with IrDA emitter/receptor module
1 : FIR uses IrDA module
0 : SIU uses IrDA module
D[0]
SIRSEL
Selects whether the SIU uses the IrDA module or the RS-232-C pins during
communications
1 : Use IrDA module
0 : Use RS-232-C interface
This register is used to set the IrDA module settings, IrDA module access privileges, and the SIU’s
communication format (IrDA or serial).
The settings of TMICMODE and TMICTX bits are valid only when IRMSEL[1..0] bits are set to 01 (TEMIC model).
