SC620 Slave Address
Following a start condition, the bus master outputs the

Current Step
SC620 is 1110 000x. The eighth bit is the data direction bit
Size (μA)
and also the least significant bit (LSB). E0h is used for a
write operation, and E1h is used for a read operation.

Dimming Control Register Description
The dimming control registers set the multiplier used to
determine the absolute current setting. Current setting for
each current sink is determined by multiplying the current
step size (as described in Table 1) by the decimal multiplier
in each dimming control register. For example, if the
current step size is set to 500μA and the L1 Dimming
Control Register bits (L1_5 through L1_0) are set to 010100
(20 decimal), then the output current for ILED1 is set to 20

x 500μA = 10mA. Note that the maximum current setting
occurs when the dimming control register bits are set to
110010 (50 decimal) - any bit combination larger than this
one will default to the maximum setting.
