Data Memory
The Data Memory is an 8-bit wide RAM internal memory and is the location where temporary
information is stored.
Divided into two types, the first of Data Memory 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 directly under program control,
however, some remain protected from user manipulation. The second area of Data Memory is
reserved for general purpose use. All locations within this area are read and write accessible under
program control.
Switching between the different Data Memory sectors is achieved by properly setting the Memory
Pointers to correct value.
Structure
The Data Memory is subdivided into several sectors, all of which are implemented in 8-bit wide
Memory. Each of the Data Memory sectors is categorized into two types, the Special Purpose Data
Memory and the General Purpose Data Memory.
The address range of the Special Purpose Data Memory for the device is from 00H to 7FH. The
General Purpose Data Memory address range is from 80H to FFH except the LCD Display and
Touch Key Module Data Memory. The LCD Data Memory is located in sector 4 with a start address
of 00H. The Touch Key Modul Data Memory is located in sector 5 and sector 6 respectively with a
start address of 00H.
