3.0
The PIC16F72X/PIC16LF72X differentiates between
various kinds of Reset:
a)
b)
c)
d)
e)
f)
Some registers are not affected in any Reset condition;
their status is unknown on POR and unchanged in any
other Reset. Most other registers are reset to a “Reset
state” on:
• Power-on Reset (POR)
• MCLR Reset
• MCLR Reset during Sleep
• WDT Reset
• Brown-out Reset (BOR)

Most registers are not affected by a WDT wake-up
since this is viewed as the resumption of normal
operation. TO and PD bits are set or cleared differently
in different Reset situations, as indicated in Table 3-3.
These bits are used in software to determine the nature
of the Reset.
A simplified block diagram of the On-Chip Reset Circuit
is shown in Figure 3-1.
The MCLR Reset path has a noise filter to detect and
ignore small pulses. See Section 23.0 “Electrical
Specifications” for pulse width specifications.
