WriteNow! models) and are explained below.
PRJ_SELx lines (input):

OK/ERRx lines (output):
Valid at the end of project execution (when BUSY is low).
Indicate, for each programming site(s), the success state
of the programming project. (OK = high, ERR = low).
The following diagram illustrates the timing for the Low-Level Interface signals.
