6.2
One time programmable memory (OTP)
The OTP contains trimming data burned at manufacturing as well as configuration bits.
Bytes from 13 to 31 (0x0D to 0x1F) are dedicated to customer settings and customer data.
They contain bits for enabling the I²C bridge, various star configuration aspects, enabling sync
via pin, SPI mode communication in MCU mode, haptic driver enabling and channel clustering.
Remaining bytes can be used to store customer LED calibration data or other data to be read
from the MCU.
At startup the OTP is copied to a RAM, so registers can be overridden at run-time and this
operation is non-persistent unless a burn follows. Since some configuration bits (eg.
SPI_mode) are read at boot, overriding them in RAM is not effective at run-time, unless a reset
telegram is issued.
