General Description
The HT48F50E is an 8-bit high-performance, RISC ar-
chitecture microcontroller devices specifically designed
for multiple I/O control product applications. Device flex-
ibility is enhanced with their internal special features
such as power-down and wake-up functions, oscillator
options, buzzer driver, etc. These features combine to
ensure applications require a minimum of external com-
ponents 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 industrial control, con-
sumer products, subsystem controllers, etc.
The device utilises a Flash type Program Memory, and
therefore have multi-programmable capabilities offering
the advantages of easy and efficient program updates.
The non-volatile internal EEPROM also offers the capa-
bility of storing information such as product part num-
bers, calibration data and other specific product
information. etc. The device is fully supported by the
Holtek range of fully functional development and pro-
gramming tools, providing a means for fast and efficient
product development cycles.

Bank 0 RAM Data Memory Structure
Bank 1 of the RAM Data Memory contains only one spe-
cial function register, known as the EECR register,
which is used for EEPROM control and located at ad-
dress ²40H² for all devices.

Bank 1 RAM Data Memory Structure
Note:
Most of the RAM Data Memory bits can be di-
rectly manipulated using the ²SET [m].i² and
²CLR [m].i² instructions with the exception of a
few dedicated bits. The RAM Data Memory can
also be accessed through the Memory Pointer
registers MP0 and MP1.
General Purpose Data Memory
All microcontroller programs require an area of
read/write memory where temporary data can be stored
and retrieved for use later. It is this area of RAM memory
that is known as General Purpose Data Memory. This
area of Data Memory is fully accessible by the user pro-
gram for both read and write operations. By using the
²SET [m].i² and ²CLR [m].i² instructions individual bits
can be set or reset under program control giving the
user a large range of flexibility for bit manipulation in the
Data Memory.
HT48F50E
Special Purpose Data Memory
This area of Data Memory, is located in Bank 0, where
registers, necessary for the correct operation of the
microcontroller, are stored. Most of the registers are
both readable and writable but some are protected and
are readable only, the details of which are located under
the relevant Special Function Register section. Note
that for locations that are unused, any read instruction to
these addresses will return the value ²00H². Although
the Special Purpose Data Memory registers are located
in Bank 0, they will still be accessible even if the Bank
Pointer has selected Bank 1.
