4D ENG2 PROG START ADDR
4D — Bits [6:0] — ADDR
Engine 2 program start address.
4E ENG3 PROG START ADDR
4E — Bits [6:0] — ADDR
Engine 3 program start address.
4F PROG MEM PAGE SELECT
4F — Bits [2:0] — PAGE_SEL
These bits select the program memory page. The program memory is divided into six pages of 16
instructions; thus, the total amount of the program memory is 96 instructions.
70H ENG1 MAPPING MSB
Valid engine 1-to-LED -mapping information can be read from ENG1 MAPPING register.
70H — Bit [0] D9
1 = D9 pin is mapped to the program execution engine 1.
0 = D9 pin non-mapped to the program execution engine 1.
71H ENG1 MAPPING LSB
71H — Bit [7] D8
1 = D8 pin is mapped to the program execution engine 1.
0 = D8 pin non-mapped to the program execution engine 1.
71H — Bit [6] D7

1 = D6 pin is mapped to the program execution engine 1.
0 = D6 pin non-mapped to the program execution engine 1.
71H — Bit [4] D5
1 = D5 pin is mapped to the program execution engine 1.
0 = D5 pin non-mapped to the program execution engine 1.
71H — Bit [3] D4
1 = D4 pin is mapped to the program execution engine 1.
0 = D4 pin non-mapped to the program execution engine 1.
71H — Bit [2] D3
1 = D3 pin is mapped to the program execution engine 1.
0 = D3 pin non-mapped to the program execution engine 1.
71H — Bit [1] D2
1 = D2 pin is mapped to the program execution engine 1.
0 = D2 pin non-mapped to the program execution engine 1.
