Detailed Description

ECC – ECC Settings register (0x001B, default 0x0000)

Bits	Name	R/W/P	Description
0-6	ECC_chsum	R/W/P	ECC checksum bits (7-bit ECC for OTP content)
7	ECC_en	R/W/P	Enable ECC protection (0 = disable, 1 = enable ECC)
8-15	(unused)	-	Unused upper bits (reads 0)

This register holds the Error-Correcting Code (ECC) for the OTP registers. To protect the custom settings, set ECC_en=1 and then program the ECC_chsum with the correct checksum before burning OTP. The 7-bit ECC checksum must be computed (read from address 0x3FD0/ECC_Checksum after enabling ECC) and written here prior to final OTP programming.
