•

Engine 1 program start address.

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.

•

•

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 = D7 pin is mapped to the program execution engine 1.

•

0 = D7 pin non-mapped to the program execution engine 1.

•

71H — Bit [5] D6

•

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.

•

1 = D1 pin is mapped to the program execution engine 1.

•

0 = D1 pin non-mapped to the program execution engine 1.

72H ENG2 MAPPING MSB

•

Valid engine 2-to-LED -mapping information can be read from ENG2 MAPPING register.

•

72H — Bit [0] D9

•

See description above for ENG1 MAPPING register.

73H ENG2 MAPPING LSB

•
