Table 38-7. EFC Self Test Cycles Register (EFCSTSIG) Field Descriptions
Bit Name Description
31–0 Signature This register is used to hold the expected signature for the eFuse ECC logic self test. It is recommended to
write a value of 0x5362F97F to this register and a value of 600 (0x00000258) to the EFCSTCY register. If
after running the eFuse ECC logic self test, the calculated signature does not match the expected
signature in the EFCSTSIG register, then a value of 18h is stored in the EFCERRSTAT register.
