Program memory – ROM
The program memory (ROM) is used to store the
program instructions that are to be executed. It
contains data, table, and interrupt entries, and
is organized into 1024
×
14 bits, 2048
×
14 bits,
4096
×
15 bits, or 8192
×
16 bits according to the mi-
crocontroller (HT48C10/ HT48C30/HT48C50/
HT48C70) selected. These bits are all addressed by the
PC and table pointer.
Certain locations in the ROM stated below are
reserved for special usage in the four microcon-
trollers except location 00CH which is used for
the HT48C50/HT48C70 exclusively.
Location 000H
Location 000H is reserved for program in-
itialization. After chip reset, the program al-
ways begins execution at this area.
Location 004H
Location 004H is reserved for external inter-
rupt service program. If the INT input pin is
activated, the interrupt is enabled, and the
stack is not full, the program begins execution
at location 004H.
Location 008H
Location 008H is reserved for the timer/event
counter interrupt service program of the
HT48C10/HT48C30 and for the timer/event
counter 0 interrupt service program of the
HT48C50/HT48C70. If the timer interrupt re-
sults from a timer/event counter overflow of
the HT48C10/HT48C30 or a timer/event
counter 0 overflow of the HT48C50/HT48C70,
and the interrupt is enabled, and the stack is
not full, the program begins execution at loca-
tion 008H.
