SNVSBD1B August 2020 – May 2024 LP8866S-Q1
PRODUCTION DATA
The LP8866S-Q1 contains several diagnostic registers than can be read with the serial interface for debugging or additional device information. Table 6-11 is a summary of the available registers.
REGISTER NAME | FUNCTION |
---|---|
FSM_LIVE_STATUS | Current state of the functional state machine |
PWM_INPUT_STATUS | Measured 16-bit duty cycle of the PWM pin input |
LED_PWM_STATUS | 16-bit LED PWM duty cycle from state machine |
LED_CURRENT_STATUS | 12-bit LED current DAC value from state machine |
VBOOST_STATUS | 10-bit value for adaptive boost voltage target — value is linear between VBOOST_MIN and VBOOST_MAX calculations |
MODE_SEL_CFG | Dimming mode configuration from MODE detection |
LED_STRING_CFG | LED string phase configuration from LEDSET detection |
BOOST_FREQ_SEL | Boost switching frequency value from BST_FSET detection |
PWM_FREQ_SEL | LED PWM frequency value from PWM_FSET detection |
