Reset
The PIC16C55X(A) differentiates between various
kinds of reset:
a)
Power-on reset (POR)
b)
MCLR reset during normal operation
c)
MCLR reset during SLEEP
d)
WDT reset (normal operation)
e)
WDT wake-up (SLEEP)
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, on MCLR or WDT reset and
on MCLR reset during SLEEP. They 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 7-4. These bits are used in software to determine
the nature of the reset. See Table 7-6 for a full descrip-
tion of reset states of all registers.
A simplified block diagram of the on-chip reset circuit is
shown in Figure 7-7.
The MCLR reset path has a noise filter to detect and
ignore small pulses. See Table 10-4 for pulse width
specification.
