PROGRAM MEMORY
Every Instruction is 16-bit width.
07H/17H/27H/37H/47H/57H
The LP55231 can store 96 instructions. Each
5F
[7:0]
R/W
00000000
instruction consists of 16 bits. Because one register
60
[15:8]
R/W
00000000
PROGRAM MEMORY
has only 8 bits, one instruction requires two register
08H/18H/28H/38H/48H/58H
addresses. In order to reduce program load time the
61
[7:0]
R/W
00000000
LP55231 supports address auto-incrementation.
62
[15:8]
R/W
00000000
PROGRAM MEMORY
Register address is incremented after each 8 data
09H/19H/29H/39H/49H/59H
bits. Thus the whole program memory page can be
63

written in one serial bus write sequence.
