27.1 Number-of-Errors Registers
The number-of-error registers determine how many errors are generated. Up to 1023 errors can be
generated. The host loads the number of errors to be generated into the NOE1 and NOE2 registers. The
host can also update the number of errors to be created by first loading the prescribed value into the NOE
registers and then toggling the WNOE bit in the error-rate control registers.
