3.2.8.1 Write Parameters

Table 3-61 describes the write parameters.

Table 3-61 Write Parameters
Parameter Bytes Description
Byte 1 Maximum red LED current (LSByte)
Byte 2 Maximum red LED current (MSByte)
Byte 3 Maximum green LED current (LSByte)
Byte 4 Maximum green LED current (MSByte)
Byte 5 Maximum blue LED current (LSByte)
Byte 6 Maximum blue LED current (MSByte)

This command sets the maximum LED currents that can be used when CAIC is enabled or disabled. When CAIC is enabled, the maximum LED currents may be further limited by the CAIC LUTs stored in the flash.
