Preliminary
Different registers are affected in different ways by
various Reset conditions. Most registers are not
affected by a WDT wake-up, since this is viewed as the
resumption of normal operation. Status bits from the
RCON register are set or cleared differently in different
Reset situations, as indicated in Table 20-5. These bits
are used in software to determine the nature of the
Reset.
A block diagram of the on-chip Reset circuit is shown in
Figure 20-2.
A MCLR noise filter is provided in the MCLR Reset
path. The filter detects and ignores small pulses.
Internally generated Resets do not drive MCLR pin low.
