change.
Some parametric limits are subject to
(1) Power-on reset
Reset can be performed automatically at power on (power-on re-
set) by connecting resistors, a diode, and a capacitor to RESET
pin. Connect RESET pin and the external circuit at the shortest dis-
tance.
Fig. 32 Power-on reset circuit example
(2) Internal state at reset
Table 17 shows port state at reset, and Figure 33 shows internal
state at reset (they are the same after system is released from re-
set). The contents of timers, registers, flags and RAM except
shown in Figure 33 are undefined, so set the initial value to them.
