Patching of program code stored in and directly executed from an OTP is supported by a patch mechanism that does not rely on additional hardware, external intervention or RAM. The features of the disclosure include using a patch daisy chain, delay considerations, non-destructive patching and nested subroutine calls. The techniques disclosed are equally applicable for OTP with an unprogrammed value of "1" as for unprogrammed values of "0". |
