7.6.1 Enable Register (Enable) (Address = 00h) [reset = 00h]

EXEC registers are synchronized to the 32-kHz clock. Delay between consecutive I2C writes to ENABLE register

(00h) need to be longer than 488 μs (typical).

Description

LOG_EN

R/W

Logarithmic PWM adjustment generation enable

CHIP_EN

R/W

Master chip enable. Enables device internal startup sequence.

See for further information. Setting EN pin low resets the

CHIP_EN state to 0. Allow 500 µs delay after setting chip_en bit

to '1'

ENG1_EXEC

R/W

Engine 1 program execution.

00b = Hold: Wait until current command is finished then stop

while EXEC mode is hold. PC can be read or written only in this

mode.

01b = Step: Execute instruction defined by current engine 1 PC

value, increment PC and change ENG1_EXEC to 00b (Hold)

10b = Run: Start at program counter value defined by current

engine 1 PC value

11b = Execute instruction defined by current engine 1 PC value

and change ENG1_EXEC to 00b (Hold)

3:2

ENG2_EXEC

R/W

Engine 2 program execution

00b = Hold: Wait until current command is finished then stop

while EXEC mode is hold. PC can be read or written only in this

mode.

01b = Step: Execute instruction defined by current engine 2 PC

value, increment PC and change ENG2_EXEC to 00b (Hold)

10b = Run: Start at program counter value defined by current

engine 2 PC value

11b = Execute instruction defined by current engine 2 PC value

and change ENG2_EXEC to 00b (Hold)

ENG3_EX

1:0

R/W

Engine 3 program execution

00b = Hold: Wait until current command is finished then stop

while EXEC mode is hold. PC can be read or written only in this

mode.

01b = Step: Execute instruction defined by current engine 3 PC

value, increment PC and change ENG3_EXEC to 00b (Hold)

10b = Run: Start at program counter value defined by current

engine 3 PC value

11b = Execute instruction defined by current engine 3 PC value

and change ENG3_EXEC to 00b (Hold)
