General Description
The Cost-Effective A/D Flash Type MCU with EEPROM
Devices are a series of 8-bit high performance RISC ar-
chitecture microcontrollers, designed especially for ap-
plications that interface directly to analog signals, such
as those from sensors. All devices include an integrated
multi-channel Analog to Digital Converter in addition to
one or two Pulse Width Modulation outputs. The usual
Holtek MCU features such as power down and wake-up
functions, oscillator options, programmable frequency
divider, etc. combine to ensure user applications require
a minimum of external components.
The benefits of integrated A/D and PWM functions, in
addition to low power consumption, high performance,
I/O flexibility and low-cost, provide these devices with
the versatility to suit a wide range of application possibil-
ities such as sensor signal processing, motor driving, in-
dustrial control, consumer products, subsystem
controllers, etc. Many features are common to all de-
vices, however, they differ in areas such as I/O pin
count, Program Memory capacity, A/D resolution, stack
capacity and package types.

Program Memory Structure
N o t Im p le m e n te d
Look-up Table
Any location within the Program Memory can be defined
as a look-up table where programmers can store fixed
data. To use the look-up table, the table pointer must
first be setup by placing the lower order address of the
look up data to be retrieved in the table pointer register,
TBLP. This register defines the lower 8-bit address of
the look-up table.
After setting up the table pointer, the table data can be
retrieved from the current Program Memory page or last
Program Memory page using the ²TABRDC[m]² or
²TABRDL [m]² instructions, respectively. When these in-
structions are executed, the lower order table byte from
the Program Memory will be transferred to the user de-
fined Data Memory register [m] as specified in the in-
struction. The higher order table data byte from the
Program Memory will be transferred to the TBLH special
register. Any unused bits in this transferred higher order
byte will be read as ²0².
The following diagram illustrates the addressing/data
flow of the look-up table:

Table Program Example
The following example shows how the table pointer and
table data is defined and retrieved from the HT46F47E
microcontroller. This example uses raw table data lo-
cated in the last page which is stored there using the
ORG statement. The value at this ORG statement is
²700H² which refers to the start address of the last page
within the 2K Program Memory of the HT46F47E
microcontroller. The table pointer is setup here to have
an initial value of ²06H². This will ensure that the first
data read from the data table will be at the Program
Memory address ²706H² or 6 locations after the start of
the last page. Note that the value for the table pointer is
referenced to the first address of the present page if the
²TABRDC [m]² instruction is being used. The high byte
of the table data which in this case is equal to zero will
be transferred to the TBLH register automatically when
the ²TABRDL [m]² instruction is executed.
