Every Instruction is 16-bit width.
The LP55231 can store 96 instructions. Each
instruction consists of 16 bits. Because one
register has only 8 bits, one instruction requires
two register addresses. In order to reduce
program load time the LP55231 supports address
auto-incrementation. Register address is
incremented after each 8 data bits. Thus the
whole program memory page can be written in
one serial bus write sequence.
