Arguments

:: String

currentMode - Parameter values: "0b0" = Full Current Mode (Default), "0b1" = Half Current Mode.

-> String

rgb0Current

-> String

rgb1Current

-> String

rgb2Current

-> Signal dom Bit

curren - enable the mixed signal control block to supply reference current to the IR drivers. When it is not enabled (CURREN=0), no current is supplied, and the IR drivers are powered down. Enabling the mixed signal control block takes 100us to reach a stable reference current value.

-> Signal dom Bit

rgbleden - enable the SB_RGB_DRV primitive. Active High.

-> Signal dom Bit

rgb0Pwm - input data to drive RGB0 LED pin. This input is usually driven from the SB_LEDD_IP.

-> Signal dom Bit

rgb1Pwm - input data to drive RGB1 LED pin. This input is usually driven from the SB_LEDD_IP.

-> Signal dom Bit

rgb2Pwm - input data to drive RGB2 LED pin. This input is usually driven from teh SB_LEDD_IP.

-> Signal dom (Bit, Bit, Bit)

(RGB0 LED output, RGB1 LED output, RGB2 LED output)

SB_RGBA_DRV primitive is the RGB LED drive module which contains 3 dedicated open drain I/O pins for RGB LED outputs. Each of the RGB LED output is bonded out together with an SB_IO_OD primitive to the package pin. User can either use SB_RGB_DRV primitive or the SB_IO_OD primitive to drive the package pin, but not both.

The primitive allows configuration of each of the 3 RGB LED outputs individually. When the RGBx_CURRENT parameter of RGBx output is set to "0b000000", then SB_IO_OD can be used to drive the package pin.

RGB Current Parameter	Full Mode Current	Half Mode Current
"0b000001"	4mA	2mA
"0b000011"	8mA	4mA
"0b000111"	12mA	6mA
"0b001111"	16mA	8mA
"0b011111"	20mA	10mA
"0b111111"	24mA	12mA
