General Description
The HT95R33 MCU is an 8-bit high performance, RISC
architecture microcontroller device specially designed
for telephone applications. Device flexibility is en-
hanced with their internal special features such as
power-down and wake-up functions, DTMF generator,
DTMF receiver, PFD driver, etc. These features com-
bine to ensure applications require a minimum of exter-
nal components and therefore reduce overall product
costs.
Having the advantages of low-power consumption,
high-performance, I/O flexibility as well as low-cost,
these devices have the versatility to suit a wide range of
application possibilities such as deluxe feature phone,
cordless phones, fax and answering machines, etc.
The device is best suited for phone products that com-
ply with versatile dialer specification requirements for
different areas or countries. The device is fully sup-
ported by the Holtek range of fully functional develop-
ment and programming tools, providing a means for fast
and efficient product development cycles.

Data Memory
The Data Memory is a volatile area of 8-bit wide RAM in-
ternal memory and is the location where temporary in-
formation is stored. Divided into two sections, the first of
these is an area of RAM where special function registers
are located. These registers have fixed locations and
are necessary for correct operation of the device. Many
of these registers can be read from and written to di-
rectly under program control, however, some remain
protected from user manipulation. The second area of
RAM Data Memory is reserved for general purpose use.
All locations within this area are read and write accessi-
ble under program control.

Structure
The Special Purpose and General Purpose Data Mem-
ory are located at consecutive locations. All are imple-
mented in RAM and are 8 bits wide. The start address of
the Data Memory is the address 00H. Registers which
are common to all microcontrollers, such as ACC, PCL,
etc., have the same Data Memory address. Note that af-
ter power-on, the contents of the Data Memory, will be in
an unknown condition, the programmer must therefore
ensure that the Data Memory is properly initialised. The
Special Purpose Data Memory is located in Bank 0
while the General Purpose Data Memory is divided into
6 individual areas or Banks known as Bank 0 to Bank 5.
Switching between different banks is achieved by set-
ting the Bank Pointer to the correct value.
