45 ENGINE1 VARIABLE A

•

45 — Bits [7:0] VARIABLE FOR ENGINE1

–

These bits are used for Engine 1 local variable. Read-only register.

46 ENGINE2 VARIABLE A

•

46 — Bits [7:0] VARIABLE FOR ENGINE2

–

These bits are used for Engine 2 local variable. Read-only register.

47 ENGINE3 VARIABLE A

•

47 — Bits [7:0] VARIABLE FOR ENGINE3

–

These bits are used for Engine 3 local variable. Read-only register.

48 MASTER FADER1

•

48 — Bits [7:0] MASTER_FADER

–

An 8-bit register to control all the LED-drivers mapped to MASTER FADER1. Master fader allows the user

to control dimming of multiple LEDS with a single serial bus write. This is a faster method to control the

dimming of multiple LEDs compared to the dimming done with the PWM registers (address 16H to 1EH),

which would need multiple writes.

49 MASTER FADER2

•

49 — Bits [7:0] MASTER_FADER

–

An 8-bit register to control all the LED-drivers mapped to MASTER FADER2. See MASTER FADER1

description.

4A MASTER FADER3

•

4A — Bits [7:0] MASTER_FADER

–

An 8-bit register to control all the LED-drivers mapped to MASTER FADER3. See MASTER FADER1

description.

4C ENG1 PROG START ADDR

•

Program memory allocation for program execution engines is defined with PROG START ADDR registers.

–

4C — Bits [6:0] — ADDR

–

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.
