USER’S MANUAL
Internal single byte or aligned word writes are guaranteed valid for synchronous re-
sets. External writes are also guaranteed to complete, provided the external configu-
ration logic on the data bus is conditioned as shown in
The logic states of certain data bus pins during reset determine SIM operating config-
uration. In addition, the state of the MODCLK pin determines system clock source and
the state of the BKPT pin determines what happens during subsequent breakpoint as-
sertions.
