Fig. 40 Internal state at reset
(2) Internal state at reset
Figure 40 shows internal state at reset (they are the same after sys-
tem is released from reset). The contents of timers, registers, flags
and RAM except shown in Figure 40 are undefined, so set the ini-
tial value to them.
“” represents undefined.
