6.1.3
The programming executive uses no Watchdog or time
out for transmitting responses to the programmer. If the
programmer does not
mechanism
Section 6.1.1 “Communication Interface and Proto-
col”, it is possible that the programming executive will
behave unexpectedly while trying to send a response
to the programmer. Since the programming executive
has no time out, it is imperative that the programmer
correctly follow the described communication protocol.
