Every Instruction is 16-bit wide.
The LP8501 can store 96 instructions. Each
5E
PROGRAM MEMORY
[15:8]
R/W

instruction consists of 16 bits. Because one register
07H/17H/27H/37H/47H/57H
5F

R/W
00000000
has only 8 bits, one instruction requires two register

LP8501 supports address auto-incrementation.
