These bits are used for Engine 1 local variable. Read-only register.
These bits are used for Engine 2 local variable. Read-only register.
These bits are used for Engine 3 local variable. Read-only register.
With hysteresis and timer bits the user can optimize the charge pump performance to better meet the requirements of the application at hand. Some applications need to be optimized for efficiency and others need to be optimized for minimum EMI, for example.
These bits are used for storing a global 8-bit variable. Variable can be used to control program flow.
INT/GPO
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.
An 8-bit register to control all the LED-drivers mapped to MASTER FADER2. Master fader allows
the user to control dimming of multiple LEDS with a single serial bus write.
An 8-bit register to control all the LED-drivers mapped to MASTER FADER3. Master fader allows
the user to control dimming of multiple LEDS with a single serial bus write.
MISC - This register contains miscellaneous control bits.
OUTPUT ON/OFF CONTROL LSB
OUTPUT ON/OFF CONTROL MSB
Program counter starting value for program execution engine 1
Program counter starting value for program execution engine 2
Program counter starting value for program execution engine 3
Program memory allocation for program execution engines is defined with PROG START ADDR registers.
Engine 2 program start address.
Engine 3 program start address.
PROGMEM page base - page selected by PROG_PAGE_SEL (0x4F)
PROGMEM page end
These bits select the program memory page. The program memory is divided into six pages of 16
instructions; thus, the total amount of the program memory is 96 instructions.
OUTPUT DIRECT/RATIOMETRIC LSB
OUTPUT DIRECT/RATIOMETRIC MSB
RESET
STATUS/INTERRUPT
TEMP ADC CONTROL
These bits are used for storing an 8-bit temperature reading acquired from the internal temperature sensor.
These bits are used for storing an 8-bit temperature reading acquired from an external sensor, if such a sensor is used.
