TC9028AP/AF
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC9028AP, TC9028AF
Infrared Remote Control Transmitting CMOS LSI with Microcontrolling
TC9028AP, TC9028AF is CMOS LSI for Infrared Remote Control
Transmitting suitable for Remote Controlling TV, VCR, Video
Disk, CD-Player etc.
Using a 4 bit Microcontroller, various transmittings are
structured by a programming.

2.5 Program memory (ROM)
Program memory stores program and fixed data. The next instruction to be executed is read from the
address indicated by the program counter.
Physical program memory doesn’t exist in addresses 300~3FFH.
When this area is read on the program, 7FH ([NOP] instruction) is read.

2.6 L register (LR)
The L register is a 4bit register. It is used as a data memory (RAM) address pointer. It can also be used
as a general-purpose register.

Timer register (TR)
The timer register is a 4bit write-only register.
It selects the mode when the timer status is read.
The timer register is initialized to 0 at reset.

IBNS
TIBS
(Initial value: 0000)
Selects number of bits to be read as timer status
0: Read 1 bit data from P53 (IT3)
At this time, the P52 to P50 data (IT2 to IT0) are 0.
1: Read 4 bit data from P53 to P50 (IT3 to IT0)
The cycle for each bit is as follows.
(Fixed)
P53: 215/fc
P52: 214/fc
P51: 213/fc
P50: 212/fc
Figure 3.4
Selects timer cycle/duty
Valid only when IBNS is 0
000: Cycle 210/fc, duty 50%
001: Cycle 211/fc, duty 50%
010: Cycle 211/fc, duty 75%
011: Cycle 212/fc, duty 50%
100: Cycle 212/fc, duty 75%
101: Cycle 213/fc, duty 50%
110: Cycle 213/fc, duty 75%
111: Cycle 214/fc, duty 50%
